A plastic ball and a ball of clay of the same weight are thrown at a wall with the same speed. The ball bounces off the wall with the same velocity as it had before while the clay ball sticks too the wall. Which object had a greater change in momentum?
-
P-momentum, m-mass, v-velocity.
In a constant mass system ΔP=mΔv. Which means change in momentum=mass x change in velocity.
As the velocity of the ball is the same after colliding with the wall, it's change in momentum will be 0kgm/s. But the velocity of the clay has changed, so there is a change in momentum.
Hope this makes sense.
