Question

when the body is acted upon by a resultant force then work done by the resultant force is equal to​

Answer 1

Answer:

Two or more opposite forces are balanced forces if their effects cancel each other and they do not cause a change in an object's motion. If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement

Answer 2

Concept

The kinetic energy of an object is a measure of the work that the object can perform as a result of its movement.

Explanation

According to the law of energy of work, the change in KE = the work done by the net (resulting) force on the body.

In other words we can say that when the body is acted upon by a resultant force then the work done by the resultant force is equal to the change in kinetic energy.

Hence the work done by a resultant force is equal to change in kinetic energy.
