Front

Force

Back

Front

Newton's First Law

Back

States that an object at rest will remain at rest, and a moving object will continue moving in a straight line with constant speed, if and only if the net force acting on that object is zero.

Front

Newton's Second Law

Back

states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated
