Which of the following best describes kinetic energy?

Kinetic energy is best described as energy in motion. This form of energy is associated with the movement of an object; the faster the object moves and the greater its mass, the more kinetic energy it possesses. It is measured using the formula ( KE = \frac{1}{2} mv^2 ), where ( m ) is the mass of the object and ( v ) is its velocity. Understanding kinetic energy is essential in many fields, including physics, engineering, and various applied sciences, as it plays a crucial role in understanding the behavior of moving objects.

The other options refer to different types of energy: one describes energy related to position, which relates to potential energy, while others refer to stored energy or energy that is changing from one form to another, further distinguishing them from the concept of kinetic energy defined as the energy an object possesses due to its motion.
