Question

kinetic energy and mass are proportional.

Explanation:

The formula for kinetic energy is \( KE=\frac{1}{2}mv^{2} \). When the velocity \( v \) is constant, as the mass \( m \) increases, the kinetic energy \( KE \) also increases in a linear relationship with \( m \) (since \( \frac{1}{2}v^{2} \) is a constant factor when \( v \) is fixed). So kinetic energy and mass are directly proportional.

Answer:

directly
