Momentum+Lab+Video+Project!

=__**Exploring Momentum Together**__=

For this project, you will be required to create a group video that explores momentum. Below is an Jing Instructional Video that will guide you through what I am looking for in this project. This will count as a lab grade. You are required to post your videos to this page and comment on two other group videos. The actual lab is provided below as well. Feel free to print the lab out. I will provide you with all of the materials for the lab a week in advance. This is designed to be a group project and when I watch the videos I expect to see whole group participation. Any calculations and explanations can be pre-written and recorded on the video so that we only need to go to one place to find all of your work. =//[|Instructional Jing Video (Watch First]//=

Mr. Stires Regents Physics Momentum Lab Materials: · Two Pasco cars, (one with spring). · 1 Stop watch · 2 Meter sticks

Part 1a: · Record the masses of both cars

Mass of Car 1(One with spring): _ Mass of Car 2 (One without spring): _ · Have both cars start at rest facing each other with spring depressed **(on first notch).** · Record the initial momentum of each car.

Initial Momentum of Car 1:

Initial Momentum of Car 2: · Push button to release spring and record the final momentum of each car. (Notice that momentum is of the system is conserved for an elastic collision.) // You will have to time how long it takes for each car to travel 1 meter and then find the velocities of each car // M1V1i + M2V2i = M1V1f + M2V2f

Part 1b: · Have both cars start at rest facing each other with spring depressed **(on second notch).** · Record the initial momentum of each car.

Initial Momentum of Car 1:

Initial Momentum of Car 2: · Push button to release spring and record the final momentum of each car. (Notice that momentum is of the system is conserved for an elastic collision.) // You will have to time how long it takes for each car to travel 1 meter and then find the velocities of each car // M1V1i + M2V2i = M1V1f + M2V2f

Part 1c: · Have both cars start at rest facing each other with spring depressed **(on third notch).** · Record the initial momentum of each car.

Initial Momentum of Car 1:

Initial Momentum of Car 2: · Push button to release spring and record the final momentum of each car. (Notice that momentum is of the system is conserved for an elastic collision.) // You will have to time how long it takes for each car to travel 1 meter and then find the velocities of each car. // M1V1i + M2V2i = M1V1f + M2V2f Part 2: · Have Car 1 sit motionlessly while Car 2 travels at a certain recordable velocity. (Use the meter stick and stop watch) · Have Car 2 hit Car 1 and record the initial and final momentums of each car and the entire system. Is momentum conserved? Why or why not? Initial Momentum of Car 1: Initial Momentum of Car 2:

· Is momentum conserved? M1V1i + M2V2i = (M1 + M2)Vf
