Electrical work involves a current transferring energy. Work done (J) = Force (N) x Distance (m) Example: During braking, a force of 2000N is applied to the brakes of a car. The car takes 20m to come to a stop.www.onlinemathlearning.com/work-done-force.htmlWork is done when energy is transferred from one store to another. Work is also done when a force causes an object to move. When work is done against frictional forces acting on an object, the object’s temperature increases. For example, a person’s hands warm up when they rub them together repeatedly.www.bbc.co.uk/bitesize/guides/z2mm8mn/revision/3If work is done on the system, the work is negative (i.e., energy added to the system). Examples of the work done by the system are, The output from the turbine. A rocket is being launched. A pump used to draw water. A vehicle running with an Internal Combustion Engine.www.geeksforgeeks.org/work-done/ - People also ask
