Newton's Laws of Motion Quiz

Which describes the First Law of Motion? There are TWO correct choices.

• F = ma

• For every action there is an equal and opposite reaction.

• An object in motion will remain in motion unless acted on by an unbalanced force.

• An object at rest will remain at rest unless acted on by an unbalanced force.

Which describes the Second Law of Motion?

• An object with more mass will require more force to accelerate.

• For every action there is an equal and opposite reaction.

• An object in motion will remain in motion unless acted on by an unbalanced force.

• An object at rest will remain at rest unless acted on by an unbalanced force.
