Introduction
Imagine a porter accustomed a amount on his head. Is he accomplishing any work? Yes, one would say! He would be paid for accustomed that amount from one abode to another. But in agreement of Physics he is not accomplishing any work! Again, brainstorm a man blame a wall? Do you anticipate he is accomplishing any work? Well, his anatomy are application and expanding. He may even be sweating.
But in Physics, we would say he is not accomplishing any work!If the porter is accustomed a actual abundant amount for a continued distance, we would say he has lot of energy. By this, we beggarly that he has lot of stamina. If a car can run at a actual top speed, we say it is actual powerful. So, we chronicle ability to speed. However, it agency something altered in Physics. Let us accept what is meant by work, ability and activity in Physics.
Work
Consider the simplest accessible case of plan done. A force ‘F’ is acting on an object. The item has a displacement ‘S’ in the administration of the force. Then the plan done is the artefact of force and displacement.
What will appear in the case if the activated force is not in the administration of displacement but rather at an bend to it. In such a case we will accede the basic of force in the administration of displacement. This basic will be able in accomplishing plan as shown.
Component of force in the administration of displacement is F Cos ?.
W = (F Cos ?) S = F. S
Work done is a scalar quantity.
