kinetic energy and mass are proportional.

kinetic energy and mass are proportional.

Answer

Brief Explanations:

The formula for kinetic energy is $KE=\frac{1}{2}mv^{2}$, where $KE$ is kinetic energy, $m$ is mass and $v$ is velocity. When velocity is constant, an increase in mass leads to an increase in kinetic - energy and vice - versa. So they are directly proportional.

Answer:

directly
