What ids gravitational potential energy ? Obtain an expression for it in case of a body of mass `m` and at a height `h` above the Earth's surface.

Define potential energy. Derive an expression for the potential energy of a body of mass m, at a height h above the surface of the Earth.

(a) Explain by an example what is meant by potential energy. Write down the expression for gravitational potential energy of a body of mass m placed at a height h above the surface of the earth. (b) What is the difference between potential energy and kinetic energy ? (c) A ball of mass 0.5 kg slows down from a speed of 5 m/s to that of 3 m/s. Calculate the change in kinetic energy of the ball. State your answer giving proper units.

Define the term potential energy, and derive its dimensions. Write an expression for the gravitational potential energy of a body of mass m raised to a height h above the earth's surface
