NEWTON LAW

  1. First law: When viewed in an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by an external force.[2][3]
  2.  Second law: \begin{smallmatrix} \mathbf{F}=m\mathbf{a} \end{smallmatrix}
. The vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the objec
  3. 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.
