Average Force:
The average force is the force exerted by a body moving at a defined rate of speed (velocity) for a defined period of time. The word 'average' is used to indicate that this is not an 'instantaneous' or precisely measured velocity.
F = m (vf - vi)/t
F = force
m = mass
vavg = average velocity
vf = final velocity
vi = initial velocity
t = time
lets conside the value of Vf = f and value of Vi = i
