Equation for calculating work done
WebWork is the scientific term used to describe the action of a force which moves an object. When a constant force is applied to move an object a distance , the amount of work performed is. The SI unit of force is the Newton, (kg m/s) and the SI unit of distance is a meter (m). The fundamental unit of work is one Newton-meter, or a joule (J). WebJan 15, 2024 · The magnitude of the force is the charge of the particle times the magnitude of the electric field F = q E, so, W 23 = q E b. Thus, the work done on the charged particle by the electric field, as the particle …
