Newtons First Law
inertia; a body at rest remains at rest and a body in motion tends to stay in motion at a constant velocity unless acted on by an outside force
Newton’s Second Law
the rate of change in the momentum of a body is proportional to the force acting upon the body and is in the direction of the force
Newton’s Third Law
‘For every action, there is an equal and opposite reaction.’ The rocket pushes exhaust gases downward, and the reaction force pushes the rocket upward.
