In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force?

Answers:

Work is equal to the change in kinetic energy.

Work depends on the square of the change in potential energy.

Work is equal to the negative of the change in kinetic energy.

Work is equal to the square of the change in kinetic energy

Work is equal to the change in kinetic energy.

Explanation:

The law relating work and kinetic energy states that "the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle."

This theorem is also called the work energy principle.

It was derived from the law of conservation of energy.

This principle stands even if there is a single force acting on the body. The change in the kinetic energy of the body is equal to the work done.

Mathematically,

W = ΔK. E.
