In every energy transformation, a small amount of energy is given off as heat. Why does this occur?
Due to friction and drag.
What is it called when many atoms are split and a huge amount of energy is released.
A chain reaction

It transforms into thermal energy at the breaks, tires, and the road.
What is Newton's law of motion?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
