Question

An object of mass 1.5 kg rests on a shelf where it has a gravitational potential energy of 7 joules. An object of mass 4.5 kg is placed on the same shelf. What is the gravitational potential energy of this second object?

Answer 1

We all know what we mean when we say a moving car has energy or the .Work is done when a force is applied on a object through a given distance. This energy is not lost, rather is stored in the box as gravitational potential energy A bucket of water with mass 10 kg is raised at constant speed to the top of a 10 meter
