 # Changing the Momentum of a Ball

Decent Essays
What is predicted to happen in this experiment is when an angle of elevation of a ramp is changed on one side this will affect the amount of momentum a ball possess before collision and after collision. The ball that travels down a ramp with a steeper angle, will have a greater velocity therefore produce more momentum because it has a greater velocity compared to the ball travelling down a ramp not as steep. This will then affect the amount of kinetic energy a ball possess after collision. The ball that is travelling down the ramp with a slightly higher angle, will possess more kinetic energy before collision but after collision it will posses less kinetic energy because of it being an elastic collision where energy is conserved and transfers some energy to the ball travelling down the less steep ramp with less momentum. Therefore the ball travelling down the ramp that is not as steep will possess more kinetic energy after collision.

In the experiment the ball that travelled down the ramp with a less steep angle of elevation rebounded further than the ball that travelled down the ramp with a slightly higher angle of elevation. This occurred because the ball did not possess as much momentum as the ball travelling down the ramp with a higher angle of elevation. Momentum is the product of an objects mass and velocity. The reason why the ball travelling down the ramp with a higher of elevation had more momentum, causing the ball to not rebound as far, was because the
