Impulse lab with homework
Impulse lab on the air track. DATA HERE Mon Dec 1 In this lab we used an ultrasound device to track position vs. time for gliders that collided on an airtrack. In this case, it was not just conservation of momentum we are looking for. It was also to show that the impulse forward for the second cart is equal to the impulse backwards on the first cart. There are equal and opposite impulses. All impulses change momentum but you can change momentum by making it smaller or by making it smaller.
Homework on Impulse
Copy of the homework on Impulse.
Fri Nov 28 Thu Nov 27 Thanksgiving recess for students) Wed Nov 26 Superintendents conference Day , no school for students Tue Nov 25
Quiz today on conservation of momentum and concepts covered in the 2 labs. Should be nice and easy. Formulas for this unit are generally limited to Momentum before = momentum after and P=mV
Mon Nov 24 Today we did the 2nd lab on momentum conservation . In this lab, we started with a total momentum of zero by starting the carts together and not moving but with a spring compressed between them. Students were to trigger the spring and use a ticker tape timer to measure velocity of the carts. By measuring the velocity and reading the mass of the carts off the side of the cart, students should be prepared to show momentum conservation.
Fri Nov 21 Thu Nov 20 Quizzes at the point of instruction have been shown to improve memory for the concepts covered. They do not have to be long but they should should be given as close to the instruction as possible. These quizzes will be graded rapidly and posted to the grades page. Make sure you are watching the results of these quizzes and that you have homework and labs turned in. Wed Nov 19 The second momentum Homework is HERE Tue Nov 18
IN class we looked at several videos involving collision in crashes.
Mon Nov 17 today we emphasize the mathematical approach to circular motion problems. . Remember to turn in the homework given to you on Friday. You should have your last quiz score posted now and make sure you are ready for the quiz tomorrow. It is as simple as using the 2 circular motion problems we have used all last week. Ac = v^2/r and Fc = m Ac You should also know that the circumference of a circle is 2 π r
Circular motion homework HERE
Fri Nov 14 I'm going to quiz you tomorrow unexpectedly. Those of you who follow whats happening on the website will not be surprised. The concept is pretty simple. In fact HERE is a copy. We will finish up you lab on circular motion and review some of the topics on your surprise quiz. Video fun for the day: Ken Brocks ultimate playground SanFrancisco A stunt driver uses centripetal force concepts to make dramatic turns in his car. This is a good time to discuss winter driving.
Thu Nov 13 We worked today on the centripetal force lab. In each class, I wanted to emphasize what is needed to write the lab up and that the lab should be written while doing the lab. This eliminates the need for delay which so often results in no lab coming in. This lab uses a rubber stopper spinning at a measured speed and used to hold up a suspended mass.
Wed Nov 12 Begin unit on circular motion. Some demonstrations: waiters crook, videos: "wall of death" "amusement park rotor""motorcycle playground fail Begin first lab on circular motion which uses a rubber stopper as the object in circular motion and steel washers as weight to balance the centripetal force.
End first Marking period. Begin Second Marking period.
Fri Nov. 7 This is the last day of the marking period. We will have a (short ) test on friction concepts. Its your last chance to shine and impress me with how much you have picked up. Make sure your labwork is in.
Thu Nov. 6 This is the 2nd last day and you will have a quiz tomorrow. We will spend the first period on practicing friction problems to model the exam Friday. The second period will be spent in the computer lab working on getting these assignments.I am still adding grades to the online system. Keep checking. Students are furiously turning in old work and I am attempting to keep up with it as it comes in. As a matter of policy in next marking period, I will be far more reluctant to accept older assignments without penalty. I try to accommodate the many activities and religious holidays but weeks after these are over is too long to wait to get these in. Next marking period I want you to focus on getting them in on time and I'll focus on getting them graded and returned quickly.
Wed Nov 5. My ability to make drawings is getting pretty bad so I made up some Smart Board slides to help outline the homework issues. I'm attaching a .pdf version of them HERE. Students generally have trouble with angles the most but both angles and horizontal surfaces are tested. Make sure you keep the same equations in mind:Ff = Fn * μ F net = m * a and Ax = A cos θIt is especially important that student THINK. Sometimes the friction is capable of being a larger force. So when we calculate the friction is 10 N , what we really mean is somewhere between 0 and 10 N : It will just take more than 10 N to make the object start moving.
Tue Nov 4.continuing our discussion of friction using coefficient of friction and normal force. Problem set done in class today for students to turn in at the end of the period. And Extra problems to do for homework. This homework is due Thursday
Mon Nov 3 Several videos involving frictional events. Some are simple low friction situations such as a Teflon fry pan or roller bearings. Some were high friction events such as drag races.
Fri Oct 24
Thu Oct 23 - Acceleration of the elevator lab. This lab measures the acceleration of the elevator both up and down. The write up does not require any graphs or interpretation of the slope. It should still follow the lab format but does not have to be typed.
Wed Oct 22 Newtons laws Homework and discussion of problem concepts. A copy of that work is attached HERE
Tue Oct 21 Another introduction to Newtons laws including the inertia concepts using bowling and soccer balls.
Mon Oct 20 Start on newtons laws with a series of online and instructional videos
Fri Oct 17 Test in class on materials to date
Thu Oct 16- Classwork on motion in 2 dimensions with 4 practice problems distributed and worked on in class. This was not Homework, It is preparation for tomorrows test. On the test tomorrow, you should see similar problems with scaffolding. That is I will , likely break the problem into steps. Copy of the work distributed HERE.
Wed Oct 15 Classwork today on projectile motions. I'm not assigning these for HW but they are the most involved of the problems for this section so I will give you a few tomorrow in preparation for a quiz Friday. Copy of what is passed out today HERE.
Tue Oct 14 New homework copy HERE on adding vectors and using graphical methods for finding resultants. Make sure you know this material. Its an easy topic to test you on and an easy topic to master. You must try and if you do, it will "click" for you. If its not clicking fast enough, make an appt. to meet me in the library after school and we'll work on it.
Mon Oct 13 Columbus day off- Probably a good time to think about myths and historical revisionism. Columbus landing in North America about 500 years after Thorfinn Karlsefni. but was one of the few explorers who managed to navigate home and return to the same spot. It was a significant accomplishment. Historical revisionists sometimes demonize Columbus and his intentions. Other have made statues of Columbus such as the one in Philadephia. Since most of the indigenous peoples likely migrated through the northern regions, its likely that some diseases that really don't survive well through extreme cold where unknown to North America. Columbus's expedition likely brought several diseases to the region at a time when disease in general was not understood.
Fri Oct 10 Begin acceleration on the 7 degree airtrack lab. In this lab, we use an airtrack which is a relatively frictionless surface to produce an acceleration along a slope. Since the angle is 7 degrees, the acceleration is a = g sin 7 , which is about 1 m/s2.We will continue the write up for this lab next week.
Thu Oct 9 vector additions problems based on former regents questions. these are due Friday and attached HERE.
Wed Oct 8 vector homework based on the samples done in class yesterday. These were to be done for homework and turned in Thursday the 9th. Copy of the Assignment HERE.
Tue Oct 7 continue instruction on vector addition. A set of samples was distributed , which we worked on in class. These were not for homework because I did them as examples
Mon Oct 6 Today we will use the double period to find both the mathematical and graphical solutions for the addition of vectors shown in the flash file below. In this animation, we can add the vectors graphically but we will also have to add them mathematically. I took the problems and added them to a word document which can be downloaded HERE.
Fri Oct 3 Today we start motion in 2 dimensions. We start first with resolving vectors into horizontal and vertical components. We finished with a homework assignment and some methods for graphically and mathematically adding 2 or more vectors. This topic will take about a week.Thu Oct 2 Students spent the first period and some of the second period obtaining data on angle of projection vs distance traveled. 7th period class had library classroom time to compile and write the lab report. 4th period, no so lucky.The write up for this experiment should include the conclusion made by the golf ball drop experiment. That is : when a golf ball is drop and thrown horizontally, simultaneously, they strike the floor at the same time. It should also conclude that the maximum time in the air is at an angle of 90 degrees but the maximum distance is at 45 degrees.
Wed Oct 1 Started on projectile motion with the rubber band cannon experiment. Key point of this experiment is to establish the link between angle of projection and characteristics of flight. Students should write the theory that suggests there is a separation between horizontal and vertical motions. They should include a data table and graph of results to show which angle produced the greatest distance.
Tue Sept 30 Test on kinematics return with instructions on how to make test corrections for credit>
Test corrections: On a separate sheet of paper:
All or Nothing:If you correct most of the problems but not all of them, You don't get credit.Circle the right answer instead of the wrong answer is NOT an explanation, no creditSeparate sheet of paper means just that. write on the test paper instead, no credit.All test correction grades use this formula: old grade * 0.75 +25 = new gradeExample: 85 *.75 +25 = 89 (4 points higher) Example: 60 *.75 +25 = 70 (10 point higher)40 *.75 +25 = 55 ( 15 point gain is 1 and 1/2 letter grades higher. Don't just call it an F. I'm not averaging Letters, I'm averaging numbers
- Describe with equations, diagrams or both why the correct answer is correct.
- If you don't know, ask someone. but don't just skip the problem because you don't understand.
- The idea is to make sure you do understand.
- If you have a lot of mistakes, you have a lot of work to do. and v.v.
Mon Sep 29 test on Kinematics in 1-D in class 2nd period
Fri Sept 26 On this double period day, we spent the 1st half on the problems set involving kinematics that was distributed Wednesday. The second half of the period, we worked in the library computer lab on free fall part II with ticker tape timers. REmember the purpose for this lab is to observe an accelerated movement caused by gravity and to find the acceleration using the slope of the velocity curve. Un like free fall in the courtyard, you should have great data for the displacement vs time graph. Both graphs should accompany your write up. The theory should address both the displacement and velocity vs time graphs. You have to able to recognize these motions on graphs.
Thu Sept 25 Today we looked at samples of kinematics problems on former regents exams. A copy of these is attached HERE. Make sure you know how to do problems of this type. I'm nervous that some of you are copying answers without any sort of standard operationg procedure for answering the questions. Remember that each problem has 5 parameters d,a,t,Vi and Vf. You must be able to find at least three of these to find an equation that will lead you to the parameter in question. Some of these are simple questions. Such as asking you if you know what distance is vs. Displacement. Some ask you to identify a scalar or a vector. - which are vocabulary terms. Most of the ones you will find difficult involve identification of the 3 variables and use of the proper equations. REmemeber to write units into your equations.
Wed Sept 24 Today we gathered free fall data in period 1 and moved to the computer lab in the second period to begin the writeup. REmember the purpose for this lab is to observe an accelerated movement caused by gravity and to find the acceleration using the slope of the velocity curve. Un like free fall in the courtyard, you should have great data for the displacement vs time graph. Both graphs should accompany your write up. The theory should address both the displacement and velocity vs time graphs. You have to able to recognize these motions on graphs.
Tues Sept 23 Free fall Part II lab this week. Copy of this lab attached HERE. It also contains a pag eon the back for how to address variation in the courtyard free fall data using averages within a spreadsheet.
Mon Sept 22 - Test today in Class on the items covered so far. Homework: P 64: 1--> 4 P 65 : 1--> 4
Fri Sept 19 - Homework: P 58: 1--> 6 P 59 : 1--> 4
Thu Sept 18 - Homework: P 53: 1--> 4 P 55 : 1--> 4 We passed out a document to work on class. Linked HERE . This is for our discussion on velocity and acceleration
Wed. Sept 17-Homework: P 47: 1--> 4 P 49 : 1--> 5today we started the kinematics concepts. We listed 5 key terms, 2 alternative terms and 3 equations.
- Displacement (D) - the difference (in meters) between where the motion starts and ends
- Acceleration (a) - Accelerations change velocity
- Time (t)
- Initial velocity ( Vi) - Velocity at the start of the motion
- final velocity ( Vf) - Velocity at the end of the motion
- Distance (d) - the Scalar version of Displacement ( a vector)
- Speed (s) - the Scalar version of Velocity ( a vector)
Tues. Sept 14 - Dropping items out of the window lab. Today, as Galileo attempted years ago, we dropped water bottles, masses and bowling balls to time how long they would take to hit the ground. We also measured the height of the window so that we could work the data into graph form . Most data were summarized by one of the students so that everyone could get it easily. There is a lot of flexibility in the data but the graph may show a visible result.Mon Sep. 13 - We did APPR pretest today. Many teachers will refer to APPR as a silly waste of time and I don't dispute that. I am seing far fewer teachers doing NOTHING than I used to see. I am, however, seeing even more great teachers stiffled in what they are able to even try because of fear. The freedom to do great things also allow freedom to goof off. There is a lot to be said for goofing off. One of the best Ted Talks I've seen is Steve Keil summary of play. Although it is aimed at Bulgaria, the science is sound and the concept is applicable everywhere
Fri. Sept 12 - Students were given a model of the quiz next week on the sig digits and math operations. Solutions are now posted. I wanted to quiz you but I didn't want to catch anyone off guard. I tried to model after the homework problems but I picked those problems I felt were easiest to grasp, but still reflected the concept. Today is a double period. We will use one of the periods to go to the computer room for putting together the lab reports. Students may either finish the first lab ( common in period 4 class who didn't get as much lab time) or start the 2nd lab report which was explained yesterday and will follow a similar write up technique. We will likely perform this lab on the next double period (tuesday)
Thu Sept 11 Your Homework assignment is out of the textbook. Ch1: page 26: 16,19-22 Remember quotient means you divide, product means multiply , sum and difference are add/ subtract.
Wed Sept 10 Today we will get more computer lab time to work on how to properly write up a lab. We also gave a sample lab write up for students to follow.
Tue Sept 9 New Homework Again on unit conversion and working with SI Units. This is 2 period day so we will use one period for the pendulum lab. We didn't get a lot done today in 3rd period because a fire drill occured mid class. We also didn't have the advantage of a computer lab this period but we hope to fix that tomorrow. The 7th period class didn't have the distraction and did get the lab time. We are a little out of sync.
Mon Sept 8 New Homework On Significant digits and working with values in SI notation. Books were distributed today and homework methods were discussed. We finished taking data for the lab and trying to head off potential homework issues. some relationships included 2.54 cm = 1.00 inch and 5280 ft = 1.00 mile. The 7th period class had opportunity to start in the library computer lab on the spreadsheet to start the write up for the lab.
Sept 5 Fri Because we didn't start gathering data for the lab, we spent the majority of the period gathering data. The emphasis today is on thinking about how to gather data. We need to gather data on length and time period for a simple pendulum. Some students found methods for making the process expedient. Students also found that holding the pendulum steady might be tough. Timing was suggested to be for 10 swings but I hope that student saw it really didn't matter if it was 10 or 2, as long as the time for each swing was accurate. I did NOT assign additional homework today.
Sept 4 Thu Students have homework on use of and work with significant digits. They also were given the first lab which could take several days to complete. A copy is provided HERE.
Sept 3rd Wed Today we opened the school year with a course requirement syllabus which gave students an overview for what was expected. They were asked to take home to parents so that parents also knew and coudl reach me at the two best places: my email is email@example.com and my cell phone is 585-314-2029
