Impulse Demonstration

Which option for catching the ball is best and why?

Preparing to Throw		Catching Option 1	Catching Option 2	Catching Option 3

As Sir Isaac Newton explained, åF = ma = m Dv/Dt

which leads to FDt = m Dv =D p     where p is the momentum

 FDt is referred to as the impulse.

We can see that the impulse is directly related to the time (Dt) over which the force acts.
