The kinetic energy of an object is directly proportional to the square of its speed. The kinetic energy (KE) is calculated using the formula KE = 0.5 × mass × velocity². This relationship highlights that as the speed of an object increases, its kinetic energy increases exponentially. For example, doubling the speed quadruples the kinetic energy, while tripling the speed increases it ninefold. This dependence on the square of the velocity emphasizes the significant impact that changes in speed can have on the kinetic energy of an object, illustrating the dynamic interplay between an object’s motion and its energy state.
The relationship between work done (W) and kinetic energy (KE) is expressed by the work-energy theorem.

According to this principle, the net work done on an object is equal to the change in its kinetic energy. Mathematically, W = ΔKE, where ΔKE represents the change in kinetic energy. When work is done on an object, transferring energy to or from it, its kinetic energy is altered accordingly. For example, if work is done to accelerate an object, its kinetic energy increases. Conversely, if work is done to decelerate or stop the object, its kinetic energy decreases, highlighting the dynamic connection between work done and kinetic energy.
