Paper 2
The unit of work done and energy transferred; one joule is the work done when a force of one newton causes a displacement of one metre along its line of action.
Specification 8.6, 8.14, 10.28 · Paper 2
The unit of work done and energy transferred. One joule is transferred when a force of one newton moves an object one metre in the direction of the force.
Revise: Work Done EquationWork done and energy are therefore both measured in joules (J); force is not energy and is measured in newtons (N).
The unit of energy and work done.
The unit used to measure energy transferred.

The unit of work done and energy transferred. One joule is the work done when a force of one newton moves an object one metre along its line of action.
Revise: Work done and energy transferThus a newton-metre represents the same amount of work as a joule.
The SI unit of energy and work done; one joule is equal to one newton-metre.
Paper 1, Paper 2
The unit of energy, with symbol J.
Revise: Kinetic and Gravitational Potential EnergyBoth quantities are measured in joules (J).
Write work done in joules: 1 N m = 1 J. When friction is involved, identify where the energy ends up rather than saying it disappears.
Write the equation, substitute values with units, then give the answer in joules.
Do not use joules for force: force is measured in newtons and work done is measured in joules.
