Question

Draw the variation of KE,PE and TE for a freely falling body

Answer 1

Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increases.The gain in kinetic energy is at the expense of the gravitational potential energy. But the total mechanical energy remains conserved.In the case of a freely falling body,consider it to be mass 'm' to be at a position A. Let 'h' be the height of the body above the reference level.
