An object at rest stays at rest, and an object in motion stays in uniform motion unless acted on by an unbalanced force. Heavier objects always fall faster than lighter ones in a vacuum. Every action has an equal reaction only when objects are at rest. Force is always proportional to the object's weight regardless of acceleration.
