Homework and Lab

  
  Please refer to WebAssign for the majority of both your homework assignments and solutions. Solutions are posted on-line after the due date. If life happens and you need adjustments made to a homework due-date or number of answer attempts please contact me. For major adjustments I ask that you complete a UEF.  
 

Group problem (9/21): Force and Friction - Note: if I see 5 proposed solutions by 5pm Monday I will post a key. Group Problem (11/2): Mechanical and Thermal Energy
Group Problem (11/9): Well Depth with Pulley and the solution key
Group Problem (11/16): Tonto and the Gold

  
 

Additional Assignments:

  
 

Rocket Movies: HINT: Right-clicking (Windows) or Control-clicking (Mac) on the videos will usually let you save the video to the computer. Then import movies into LoggerPro to analyze.

Dr C's posting          

Some suggestions, courtesy Dr C, for processing your video and time data:

  1. Remember that the videos were shot at 1200 frames per second.
  2. Remember you can use the length of your rocket or the meter long tube to set the scale of the video, so that the output of position, velocity, and acceleration is in physical units.
  3. Remember, you launched the rocket from a few inches off the ground and the ground was not perfectly even, don't expect your model to get a perfect flight time, although it should be close.
  4. Remember, you are comparing the flight time and initial launch acceleration of your computer model to reality. You will need to have estimates with error bars for both quantities in order to compare them to the computer model.
  
  

Exam Examples

Use the tests below to practice. The best way to practice is to take the test and then look at the answer key. If you just look at the answer key you actually do not learn. The sample tests below are based on a different textbook so the order of the content covered is slightly different than our current textbook. Hence, your actual exam will be similar in format but the content coverage will differ. Note: You get most of the points not for a correct choice on a multiple choice problem but rather for explaining your choice correctly.

It is often good to create a summary of useful concepts and equations for yourself as a study guide. There are many useful concepts/equations avaiable that you can find... however, if you do not create it yourself you have robbed yourself of a learning opportunity.

Quiz #1 Programming Quiz
 The first quiz was a check on your comfort level with programming - both syntax as well as coding actual physics. As a quick check, your score reflects more your participation than your expertise. You should only check the quiz key after completing the quiz.
