Answer» First law:In an INERTIAL frame of reference, an object either REMAINS at rest or continues to move at a constant velocity, unless acted UPON by a force.[2][3]Second law: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. (It is assumed here that the mass m is constant – see below.)Third law: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. |
