Question

What is transferred when work is done?

Answer 1

Work done:

1. Work done is defined as the multiplication of the magnitude of displacement and the component of the force that is in the direction of displacement.
2. Mathematically: Work done $\left(W\right)=F.s$, Where $F=$Force, $s$= displacement,

Energy:

1. When work is done, energy is transferred from the agent to the object, which results in a change in the object's motion (more specifically, a change in the object's kinetic energy).
2. When a force causes a body to move, work is done on the object by force.
3. Work is the measure of the energy transfer when a force moves an object through a distance.
4. So we say that energy is transferred from one energy store to another when work is done, and therefore, the energy transferred = work done.
5. For example, a fan converts electrical energy into mechanical energy. In the heater, electrical energy is converted into heat energy, etc.

Thus, energy is transferred when work is done.
