Name Jimmie Parker Date: Nov,14,2023 School: Greensboro high school Facilitator: 6.07 Elastic Collision Lab Use the Collision Carts interactive linked on the Task page to complete the following virtual lab. Be sure to complete all 4 parts of this lab. Part 1: Preparation 1. Open the Physics Classroom Collision Cart interactive. Select the double arrow button in the top left of the interactive to resize. 2. Select the Elastic Collision option at the bottom of the screen. 3. To learn how the interactive works, experiment with the following: a. Change the Mass and Initial Velocity of the two carts and select the black Start button at the top right of the screen. Try several combinations of mass and initial velocity. b. Change the position of the carts by dragging them to different parts of the track and seeing how it impacts the collision. c. Make sure you know where the Start, Pause, and Reset buttons are on the screen. Part 2: Elastic Collision 1 For the first collision, the blue cart will initially be at rest. BEFORE COLLISION AFTER COLLISION 1. Initial Velocity a. Set the initial velocity of the blue cart to 0 m/s. b. Change the initial velocity of the red cart to whatever value you prefer. Record the initial velocity of the red cart here: 5 m/s. 2. Mass: You will determine the mass of each cart for this collision. Change the mass for each cart and record it below: a. Red cart: m = 1 .00 kg b. Blue cart: m = 1 . 0 0 kg

3. Once you have the mass and initial velocities set, run the simulation. Record the final velocity: a. Red cart final velocity: 0.00 m/s b. Blue cart final velocity: 5.00 m/s 4. Complete the table below about your collision simulation using the data you have collected. You will need to complete calculations to determine change in momentum. Elastic Collision 1 Before Collision After Collision ∆Momentum (Δp) Red Cart 1.00 kg x 5.00 m/s = 5.00 kg•m/s 1.00 kg x 0.00 m/s = 0.00 kg•m/s 0.00 Blue Cart 1.00 kg x 0.00 m/s = 0.00 kg•m/s 1.00 kg x 5.00 m/s = 5.00 kg•m/s 5.00 System Total 0.00 0.00 0.00 Part 3: Elastic Collision 2 For the second collision, the blue cart will be moving slower than the red cart. BEFORE COLLISION AFTER COLLISION 1. Initial Velocity a. Change the initial velocity of the red cart to whatever value you prefer. Record the initial velocity of the red cart here: 5 . 0 0 m/s. b. Change the initial velocity of the blue cart to any values less than the red cart velocity. Record the initial velocity of the blue cart here: 2 .00 m/s.

Momentum was conserved and was transferred from the red car to the other and with greater mass it converted some of its speed to the blue car. If the red car didn't have more mass to it the blue car would probably travel not as far as it did with more kg. Therefore, momentum was conserved until the fullest of momentum.
