What is work done and its SI unit?
S.I. unit of work is Joule. Work done when a force of 1 Newton displaces the body through a distance of 1 metre in the direction of force.
What happens to the body on which work is done?
Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to the motion of the object, the work is considered to be negative, implying that energy is taken from the object.
What is understood by work in 100 words?
In physics, work is the product of force and displacement. A force is said to do positive work if (when applied) the force has a component in the direction of the displacement of the point of application. Work transfers energy from one place to another, or one form to another. The SI unit of work is the joule.
