Calculation Involving Work Done - JSS2 Basic science Lesson Note

Work done is the transfer of energy from one object to another when a force is applied over a distance. It is calculated as the force applied multiplied by the distance moved in the direction of the force. 

So, if you push a box with a force of 10 Newtons for a distance of 5 meters, the work done would be 50 joules (10 N * 5 m).

This work done can change the object's energy, either increasing its kinetic energy if it's in motion or potential energy if its position changes.
