Quizplus · Accepted Answer

The kinetic energy (KE) of an object is given by the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity. This formula does not depend on the force applied, the distance moved, or the time interval, only on the mass and the velocity of the object.
