Question

Work done on an object is defined as the product of the magnitude of the force acting on the body and

the displacement in the direction of the force. W = F.s Energy is defined as the ability to do work. Its

unit is the same as that of work. SI unit of energy or work = Joule (Nm) .Consider a ball falling freely from

a height, energy gets transferred from PE to KE, while the total energy remains the same. The SI unit of

power is Joules per Second (J/s), which is termed as Watt. Watt can be defined as the power taken to do​

Answer 1

Answer:

The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force. ... The SI unit of work Nm = Joule (J). Work is the "scalar product" or "dot product" of the force and the displacement vector.
