What is kinetic energy a measure of?

Stored energy

Energy of motion

Kinetic energy is defined as the energy that an object possesses due to its motion. When an object is moving, it has the capacity to do work as a result of its velocity and mass. The formula for kinetic energy is given by \( KE = \frac{1}{2} mv^2 \), where \( m \) is the mass of the object and \( v \) is its velocity. This relationship illustrates how an increase in speed or mass will result in a greater amount of kinetic energy. Understanding kinetic energy is crucial in various physical science applications, such as mechanics, where the movement of objects plays a vital role in energy transformations and dynamics.
