Question

proove that
proove that PE=mgh

Answer 1

send the question .What we have to prove?

Answer 2

That is very simple.

E=Fd(up to class ix)
f=ma
if the body is at hight then a will =g
f=mg(i)
putting on the above equation
e=mgd
since the body is at a distance of its height
so
e=mgh

here the energy in the body is its potential energy gained because of its height
so
PE=mgh


Hope u got that
