Question

define work energy therom with thier expression​

Answer 1

Answer:

The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.

more,

The work-energy theorem also known as the principle of work and kinetic energy states that the total work done by the sum of all the forces acting on a particle is equal to the change in the kinetic energy of that particle

Work energy theorem states that the change in kinetic energy of an object is equal to the net work done on it by the net force. Let us suppose that a body is initially at rest and a force. is applied on the body to displace it through. along the direction of the force

Answer 2

Work energy theorm:

The net work done by the forces on an object is equal to the change in its kinetic energy.

Expression:

$W = \frac{1}{2} mv_{f} ^2 - \frac{1}{2} mv_{i} ^2$ = Change in kinetic energy of body

Vf = Final velocity

Vi = Initial velocity

m = mass

Mark as brainliest if it helped : D
