Solve the question please ??????????????????please
Solution :
(9.) If an object of mass 'm' is raised to a height of 'h' above the ground, the amount of work done will be equal to mgh.
This amount of energy is transferred to the object in the form of potential energy.
Work done = Fd
where, F = force
d = displacement
Now,
F = mg (mass × acceleration or gravity)
So,
W = mg × h
W = mgh = Potential energy
(8.)
Gravitational potential energy:
Gravitational potential energy (U) is the amount of work done against gravity to take a body away from the earth's surface (where h = 0).
U = - GMem/r
where, Me = mass of the Earth
m = mass of the object
r = distance between the centre of the earth and the object
