That's right - you got saved by the lab! Quiz is moved to tomorrow, but measurements and calculations MUST be finished TODAY.
Remember: what information should you collect first? What should each of the collisions look like physically, based on your notes? How will you achieve the Big Three Lab Goals?
Learning Goal: I can...
- ...predict accurately how a force exerted on an object changes the object’s momentum
- ...I can accurately relate Newton’s second and third laws to momentum.
Today: Momentum & Energy in Collisions
Given: Air track set, various sensors
Find: Design an experiment to investigate conservation of momentum and conservation of energy using an air track set. One of your goals from this lab is to be able to determine the type of collision (either elastic or inelastic) based on data analysis.
- Add at least some mass to your cart. This may help reduce the impact of friction on your data.
- Your finished product should include accurate LOL charts as well as energy and momentum summations.
- Have data for at least one example of each type of collision.
- Show the energy summation and the momentum summation for each collision.
- Write a brief summary/conclusion of what you observed about the momentum and energy of collisions. Refer to the data.
- If you are not satisfied with the results of the Momentum Summative, remember: DO NOT WAIT! See me ASAP to discuss preparations for a retake. If it will be urgent in May, it should be urgent today!
