A body of mass m is moved from the ground to a height h. If the force of gravity on mass of 1kg is g newton Find:
(a) the force needed to lift the body
(b) the work done in lifting the body
(c) the potential energy stored in the body​

Answer:

(a) When a body of mass m at A on ground is raised above ground through height h at B, force is applied.

Force applied = weight of body

Force on mass m = F = mg

‘g’ is the acceleration due to gravity on a mass of 1 kg

(b) Work done = Force \times× displacement (distance)

W = mgh

(c) The work done is stored in body in the form of potential energy

P.E = mgh

hope it help
