Newton's Law of Motion

A rocket pushes burning gases DOWN which causes the rocket to launch UP. Which law is this?

• Newton's 1st Law - Law of Inertia

• Newton's 2nd Law - Law of Acceleration

• Newton's 3rd Law - Law of Force Pairs (Action, Reaction)

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

• Law of Force Pairs

• Law of Acceleration
