In conservative force, Force is the _________ gradiet of Potential energy.

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.

Kinetic energy of the body is always

Rotational Kinetic energy of a body is

When the body is disturbed, the potential energy remains same, then the body is in

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

When a force is applied on a body, it can change
