### How to Calculate the Force of a Falling Object | Sciencing

The force is equal to the rate of change of momentum, so to do this you need to know the momentum of the object before and after the bounce. By calculating the change in momentum between the fall and the bounce and dividing the result by the amount of time between these two points, you can get an estimate for the impact force.

### Impact Force from Falling Object Georgia State University

If an object of mass m= kg is dropped from height h = m, then the velocity just before impact is v = m/s.
