State the work-energy theorem.

A body of mass $m$ is moving with a uniform velocity $u$. A force is applied on the body due to which its velocity increases from $u$ to $v$. How much work is being done by the force?

A light mass and a heavy mass have equal momentum. Which will have more kinetic energy?

Name the three forms of kinetic energy and give one example of each.

State two differences between potential energy and kinetic energy.

The kinetic energy of a body is the energy by virtue of its _____. (motion, position)

The potential energy of a body is the energy by virtue of its _____. (position, motion)

Name the form of mechanical energy, which is put to use when a body is in motion. (Kinetic energy/ Potential energy)
