WORK

  • The force is acting in the direction of displacement.
  • Work to be equal to the product of the force and displacement.
  • Work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force. Work has only magnitude and no direction.
  • Let a constant force, F act on an object. Let the object be displaced through a distance, s in the direction of the force.
  • Work done = force × displacement W =Fs
  • Units= N m unit of work is newton metre (N m) or joule (J).
  • Workdone,W = F×s=mg×s
