What is Newton's second law of motion?

• What goes up must come down

• For every action there is an equal and opposite reaction

• Force equals mass multiplied by acceleration

• An object in motion stays in motion at the same speed and direction Unless acted on by an unbalanced force

What is Newton's first law of motion??

• An object in motion stays in motion at the same speed and direction Unless acted on by an unbalanced force

• Force equals mass multiplied by acceleration

• What goes up must come down

• For every action there is an equal and opposite reaction
