Misunderstanding about work definition

  1. Apr 2, 2010 #1
    as scientists defines it work is the product of force and displacement i just want to ask is the displacement meusured during force application or during motion even if the force removed
    thank you

    It's measured during the force's application, and the displacement is measured in the direction of the applied force.

    It's important to ensure you consider the correct force though.

    For instance if you push something and initiate motion so it rolls or slides away, although your push has ceased, the force of friction is still acting.
