Newton's First Law of Motion: In an initial frame of reference an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

Newton's Second Law of Motion: In an inertial frame of reference, the vector sum of the forces (F) on an object is equal to the mass (m) of that object multiplied by the acceleration (a) of the object: F = ma

Newton's Third Law of Motion: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
