Free Fall Equation Physics. V t = g t. V f = (9.8 m/s 2) * (8 s) = 78.4 m/s.
Find the forces acting on the object. When this happens, an object may be falling, but it is not in free fall. For a freely falling object, we have the free fall kinematics equations:
I think the differential equation should look like this:
H = ½ g t2. V t = g t. The force acting during free fall motion is equal to the force of gravitation between the falling body and the earth therefore we can put this in the form of an equation, f = \[\frac{gmm}{(r+h)²}\] Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g.
