6.5.2 Work done and energy transfer
| Content | Key opportunities for skills development |
|---|---|
When a force causes an object to move through a distance work is done on the object. So a force does work on an object when the force causes a displacement of the object. | |
The work done by a force on an object can be calculated using the equation: (moved along the line of action of the force) |
work done, W, in joules, J
force, F, in newtons, N
distance, s, in metres
MS 3b, c Students should be able to recall and apply this equation. |
One joule of work is done when a force of one newton causes a displacement of one metre. 1 joule = 1 newton-metre Students should be able to describe the energy transfer involved when work is done. | WS 4.5 |
Students should be able to convert between newton-metres and joules. Work done against the frictional forces acting on an object causes a rise in the temperature of the object. | MS 1c WS 4.5 |
