Match the following

Newton's 2nd Law

A net force acting on an object causes the object to accelerate in the direction of the net force

Newton's 1st Law

An object will move at constant velocity until a net force acts on it

Newton's 3rd Law

All moving objects have momentum. Momentum is transferred between objects in a collision

Law of Conservation of Momentum

Every action as an equal and opposite reaction
