Lab 5 Momentum and Collisions Objective: To learn about conservation of momentum in different types of collisions. Materials: Vernier Dynamics Track Standard carts, 500 g standard lab mass Introduction: Momentum \"p\" is defined as the product of the mass \"m\" and the velocity \"v\" of the object. Momentum is a vector. It can be in positive or direction depending on the direction of the Velocity of the object. External forces produce a change in the momentum of an object. If we consider as our system two carts that undergo a collision, then any forces they exert on one another are internal to the system. IN this experiment, we will examine the conservation of momentum in case of Elastic collisions and in Completely Inelastic Collisions. Procedure: Please watch the video and complete the calculations using the data provided to confirm whether momentum and Kinetic energy are conserved in case of elastic and completely inelastic collisions or not. Data: Part 1: Elastic collisions _{1 point per three boxes) 1. Use the tables below to help with your evaluation of the momentum before and after the collisions of the carts. 1= T =] [ Tosw0 | oss | 0 [ osw] o | oser | [ 2 | 101 | o032 [ odo1 | osto] o | o4 | [ s Joswo ] o4 | oosss | 101 ] o | o246 | [ 0252 | o066 | n- 0.205 0.038 0510 | 0.199 0.290 2. How does the total momentum of the system after collision compare with that before the collision? Do your results agree with your expectations? Explain. (1 point) 3. Calculate the kinetic energy KE=1/2 (mv') of the system (for one the above runs) both before and after each of the callisions. How do the quantities compare? Show your calculations. (1 point) 2.

How does the total momentum of the system after the collision compare with that before the collision? Is the agreement in these inelastic aollisions as good as that in the elastic collisions? Try to account for these differences. (1 point) 3. Calaulate the total kinetic energy of the system (for one of the above runs) both before and after each of the aollisions. How do these quantities compare? Compare your findings with those of others in your dass. (1 point)
