The correct formula for calculating kinetic energy is given by the expression that states kinetic energy (KE) is equal to one-half of the mass (m) multiplied by the velocity (v) squared, expressed as KE = ½ mv².

This formula illustrates that kinetic energy depends directly on both the mass of the object and the square of its velocity. The factor of one-half is crucial as it relates to the energy due to motion. The mass represents how much matter an object contains, while the velocity squared indicates that as an object's speed increases, its kinetic energy increases exponentially since it's squared in the equation. This is a fundamental principle in physics that delineates the relationship between motion and energy.

The other options do not represent kinetic energy. They either describe potential energy or have incorrect mathematical relationships for kinetic energy. Understanding that kinetic energy is specifically associated with an object's movement is crucial for applying physics principles effectively.
