Question

1. A body of mass m is moved from ground to a
heighth. Ir force of gravity on mass of 1 kg is g
newton, find : (a) the force needed to lift the body ,
(b) the work done in lifting the body and (c) the
potential energy stored in the body,
​

Answer 1

Explanation:

When a body of mass at a on ground is raised Above ground through height at B force is applied this force applied = weight of body . (b) Work done in lifting the body = Force x displacement = mg x h . (c) This work done w stored in body the form of potential energy P.E.

Answer 2
