Which statement about kinetic energy (K.E.) is true?

Question

Quizplus · Accepted Answer

Kinetic energy (K.E.) is given by the formula $K.E. = \frac{1}{2}mv^2$, where $m$ is the mass and $v$ is the velocity of the body. This formula shows that K.E. is directly proportional to the square of the velocity and also depends on the mass of the body. Therefore, if the velocity of a body doubles, its K.E. will quadruple, not double (eliminating A). K.E. increases with an increase in velocity, not decreases (eliminating B). K.E. is dependent on the mass of the body (eliminating C). Objects moving with the same velocity can have different K.E. if their masses are different (eliminating D).
