Question

Derive an expression of potential energy of body mass m and moving with acceleration g from height h?

Answer 1

PE of a body of mass m falling from a height h under g =mgh

Answer 2

Here is your answer...

We know, energy is the capacity to do work.

So, Work done =Energy required

Now, W =F×s

=(m×a)×s

=m×g×h

Since,W=P.E

Therefore, P.E =m×g×h

Hope this helps you...
