A body of mass 6 kg is kept at a height of 5 m from the surface of earth. Find the potential energy of the body.

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy ? If the object is allowed to fall, find its kinetic energy when it is half-way down. Take g = 10 ms ^-2 .

Name the term used for the sum of kinetic and potential energy of a body.

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0Xx10^24 kg , radius = 6400 km.

A body of mass 2 kg is thrown up at a velocity of 10 ms. Find the kinetic energy of the body of the time of throw. Also find the potential energy of the body at highest point.

Name the term used for the sum of kinetic energy and potential energy of a body.
