In Physics, 'work' has a very clear definition:
It's (strength of a force) times (distance through which the force acts).
'Work' has the units of Energy.
If you push against a shopping cart with 30 newtons of force, and you keep pushing while the cart moves 4 meters, then you have done (30 x 4) = 120 newton-meters of work = 120 "Joules".
In physics, work is defined as the energy transferred when a force moves an object over a distance. It is calculated using the formula W = F ยท d, with work measured in joules. For work to occur, a force must be applied, and the object must be displaced in the direction of that force.
