![]() With a small amount of friction present its magnitude probably decreases, but only by a small If friction were completely negligible, the total momentum should not change. In a real car collision, this would be the opposite of the firstĭetermine the momentum of each cart and the total momentum of both carts before andĪfter the collision. ![]() Momentum and Newton’s third law it says that every action or force there is an equal This is what I expected because the impulse is the change in With more interaction time, there would be less collision damageĪnd less impact. With less interaction time, there would be more force which can cause a much largerĪnd worse collision. Is this what you expected? What significance might this have in a real car collision? Compare maximum forces and the interaction times for the four different collisions.Want to reduce the impact so the collision would be smaller. In a real car collision, this example would have significance because we would Shows that it could have a smaller collision time than the other materials that were The impulse for aluminum is lower than the force which Is this what youĮxpected? What significance might this have in a real car collision? Explain. Compare the impulse using the four different bumper blocks. ![]() Bumper block Aluminum Wood High-Density foam Low-density foam Maximum force 12 N 11 N 9 N 7 N Collision time.
