Full Answer

Work involves the application of force on an object that causes movement across a distance. For example, pushing a shopping cart involves exerting force to move it over the ground. The basic equation to illustrate this is:

  • Work done = force x distance, or
  • W = F x d, with W being work done in joules, F being force in Newtons and d measured in meters.

The activity of work essentially involves the transfer of energy. In the previous example, energy is transferred from a person to the shopping cart.
