If the force acting on a body is inversely proportional to its speed, the kinetic energy of the body is:

Rotational Kinetic energy of a body is

A body of mass m is thrown vertically upward with a velocity v. The height at which the kinetic energy of the body is one third of its initial value is given by

Assertion : When Air is blow on a plastic cover, lying on the floor. If flies to a particular height in different directions. Also It's energy at different positions keep changing. Reason : Work done by the force on the body changes the kinetic energy of the body. This is called Work - Energy Theorem. i.e., W = Delta K.E.
