1.2 Impact Forces
What happens to the impact force (and why?) if the duration of impact is reduced? How do we calculate Δ(mv) for a moving object which stops or reverses? What happens to the momentum of a ball when it bounces off a wall?

Starter activity.....
Using Newton's second law which states; Force is proportional to the rate of change of momentum Can you derive the formula F = ma and explain why this is the
case?

Impact Times

Starter activity.....
• Using the ideas of momentum that you have just covered can you explain the momentum and rebound impacts at normal angles and at other angles.
• Also what will happen to the impact force of a gas particle on a wall when the angles change?
