Question

define heat in your own words.
write what you know about kinetic energy (k.e.)

Explanation:

Heat is energy transferred due to temperature difference. Kinetic energy is energy of motion, $KE=\frac{1}{2}mv^{2}$.

Answer:

Heat: Energy transferred by temperature - difference.
Kinetic energy: Energy of an object in motion, formula $KE = \frac{1}{2}mv^{2}$.
