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.

Derive an expression for the potential energy of a stretched spring .

Derive an expression for the potential energy of an elastic stretched spring.

If the potential energy of a body at a height h from the surface of the earth is (mgR)/(2) , then

What is the gravitational potential energy of a body of mass m at a height h ?

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 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

At a height H from the surface of earth, the total energy of a satellite is equal to the potential energy of a body of equal mass at a height 3R from the surface of the earth (R = radius of the earth). The value of H is

" The potential energy of a body of mass "m" on the surface of earth is "
