WORK

When a force acts on an object and the object moves, scientists say work has been done. If you lift your school bag, full of heavy books, onto your shoulder, then you are doing work. However, no matter how large the force is, if there is no movement than no work has been done.

If work is done on an object then the object gains energy. The gain in energy by the object equals the work done on the object. Both work and energy are measured in Joules (J). Work is calculated using this formula: W= F x D where W is the work in Joules, F is the Force in newtons and d is the distance in the direction of the force, in metres.
