The definition of the ability to do work due to an object's motion aligns with the concept of kinetic energy. Kinetic energy is the energy possessed by an object because of its velocity; that is, it is directly related to the object's mass and speed. The formula for kinetic energy is ( KE = \frac{1}{2} mv^2 ), where ( m ) is the mass of the object and ( v ) is its velocity. When an object is in motion, it can perform work on other objects, which is precisely the reason why kinetic energy is associated with the ability to do work.

Power, on the other hand, refers to the rate at which work is done or energy is transferred, and while it relates to motion, it does not directly define the energy due to the motion of an object. Potential energy refers to the energy stored in an object due to its position or state, and force is a vector that causes mass to accelerate but does not define energy itself. Each of these concepts plays a role in understanding energy and motion but not as directly linked to the definition of work due to motion as kinetic energy does.
