Newton’s 2nd Law


Written by      First published July 19, 2008      Last modified August 25, 2011

If Fnet is the net force acting on an object of mass m, then the aceleration (a) follows the equation:

Fnet = ma

  • Fnet is the sum of all forces acting on the object.
  • If Fnet = 0, then a = 0.
  • A force of 1 kgºm/s² is 1 netwon (N).
