Answer 1

Answer:

As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. If an object is dropped from height h = m, then the velocity just before impact is. v = m/s.

Hope it will help you.

Answer 2

Answer:

Law of conservation of energy - Energy can neither be created nor be destroyed; it can only be transformed from one form to another. Consider a body of mass m placed at A. h = AB is the height of the body above the ground. u = 0 is initial velocity at A. v1 = velocity of body at C.
