Energy Transfer

What is Work Done?

"Work done" is another way of saying "energy transferred".
Work done = Energy transferred.            W = E

The equation that connects work, force and distance is

Work done = Force x Distance.        W = F x d

The equation can also be written as

Energy = Force x Distance.         E = F x d

These equations are important!

Strictly speaking, work done = force x distance
is only true when the distance moved by the object
is in the direction of the force. This is the
case for all of the examples you will meet at GCSE.
