Unformatted text preview: Data recording will commence when the cart collides with the bumper. Click stop after the cart rebounds from the collision. Uncertainty: A./B. Any uncertainty would have been caused by the track not being level giving one of the carts extra momentum. Also, if the participant gives one or the other carts too much of a push, it could skew the results. C. Uncertainty could have been caused by not using the same position for each of the trials. Conclusion: After determining the total amount of momentum of the carts before and after collisions our results in each of the trials exhibit the principles of conservation of momentum. This was that if the net forces were ignored the sum of the momenta of the two carts prior to collision is the same after the collision....
