Reference: OCR
Calculated with W = F × s, where force is in newtons and distance moved in metres along the line of action of that force, giving the answer in joules (J).
Energy transferred by a force, and in a circuit the source does it pushing charge round the loop while the charge does it passing through each component.
Measures the energy transferred when a force moves an object, calculated as force in newtons multiplied by distance in metres, in joules.
Braking force multiplied by braking distance, so a smaller force means the distance must be larger.
Equal to braking force × braking distance, and must equal the kinetic energy of the vehicle.
The transfer of energy by a force moving its point of application through a distance.
