Recall the formula for impulse and the relationship to change in momentum:

The impulse - momentum theorem states that the impulse exerted on an object is equal to the change in its momentum , i.e., . If the force acting on an object is constant over time, the change in momentum will be the same over equal time intervals.

Analyze each type of motion:

Free - fall motion:

In free - fall motion, the only force acting on the object is the gravitational force , where is the mass of the object and is the acceleration due to gravity ().

The force is constant. According to the impulse - momentum theorem , for equal time intervals , the change in momentum
