Answer:

Velocity

Explanation:

We know that in Classical mechanics,
Kinetic energy #KE=1/2 "mass"*"velocity"^2#
From this expression we see that

#KE prop "mass"#
i.e., Kinetic energy is directly proportional to the mass.

Also #KE prop "velocity"^2#
i.e., Kinetic energy is proportional to the square of the velocity.

Hence, the answer.
