    Work done.

    Explanation:

    The work energy theorem (also called the principle of kinetic energy and work) tells us that the change in the kinetic energy of a body is equal to the work done by the force acting on a body.

    If there is more than one force acting on the body, then the change in kinetic energy is equal to the work done by the sum of forces acting on the body.

    Mathematically, it states that:

    Δ K. E. = W

    Where W = work done

    The work done is given as the product of the force acting on the body and the distance moved by the body.

    Δ K. E. = F * d

    If there are multiple forces, it would be:

    Δ K. E. = ΣF * d
