If the kinetic energy of an object increases, then
A) the potential energy must decrease.
B) the total energy must increase.
C) there can only be one force on the object.
D) the speed must increase as well.

Question

Quizplus · Accepted Answer

Kinetic energy is directly related to the speed of an object, as it is defined by the equation $KE = \frac{1}{2}mv^2$, where $m$ is the mass and $v$ is the speed of the object. Therefore, if the kinetic energy increases, the speed of the object must also increase.
