Question

A body of mass m is moved from ground to a hieght h.If Force of gravity on mass 1 kg is g Newton, find:(a) the force needed to lift the body and (b) the work done in lifting the body and(c) the potential energy stored in the body?

Answer 1

Work = force × displacement
m ×a × s = mgh
Force = m×g
Potential energy = mgh

Answer 2

Answer:

hiii,

HOPE IT'S HELPFUL to you........
