A body is projected vertically upwards from the ground with a velocity of 20 m/s. If the potential energy of the body at a height of 5 m from the ground is 100 J, then the kinetic energy of the body at a height of 10 m from the ground will be: (Take g = 10 m/s2)

Raising an object from the ground results in the storage of which type of energy?

Positive work is done by a force when the displacement of the body is:

A box is pushed with a force of 20 N across a horizontal floor for a distance of 5 m in the direction of the force. What is the work done by the force?
