1.

a)Define kinetic and potential energy of a body. Give their S.I. units.b)A block of mass 10kg is released from a height 10m from rest state. It fallsfreely. Taking floor as reference position for potential energy, calculate itskinetic and potential energy when it is at height 4m from the floor(Take g = 9.8ms-2)

Answer»

si unit energy of both the energy is joule. KINETIC energy of a body in motion. and potential energy is the energy stored in the body
