Energy extracted by braking. Can be regarded as brake wear - a pair of standard bicycle disc brake pads will last around 50 MJ, for cars around 5 GJ.
Enerxía extraída pola freada. Pódese considerar como desgaste dos freos: un par de pastillas de freo de disco de bicicleta estándar durarán uns 50 MJ, para coches duns 5 GJ.
Power exerted during activity, due to drag forces, altitude change, etc. Negative means power gain, e.g. when going downhill or braking. When in kcal/h or kJ/h, it also takes efficiency and BMR into account.
