Meenu observed that as a stone of mass 1kg falls freely from a height 1m, its potential energy gets converted into kinetic energy. Therefore, its potential energy decreases and kinetic energy increases. As the stone touches the ground, all its potential energy is converted to the kinetic energy.

State the law of conservation of energy.
A ball is dropped from a height of 10 m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back?
A body is falling from a height h. After it has fallen a height h/2, it will possess
The weight of a person on a planet A is about half that on the earth. He can jump upto 0.4 m height on the surface of the earth. How high he can jump on the planet A?
