Question

what is the relationship of work and energy

Answer 1

There is a strong connection between work and energy, in a sense that when there is a net force doing work on an object, the object's kinetic energy willchange by an amount equal to the work done: Note that the work in this equation is the work done by the net force, rather than the work done by an individual force.

Answer 2

For an object to work, there must be a force acting on it and the object should move in the direction of the force. Why does an object move when a force is applied on it ? It is because the force increases the level of energy of the object. It gives the object the ability of capacity to move in the direction of the force. When we push a ball lying on the ground, the ball moves forward. In fact , we do work on the ball and the ball acquires kinetic energy.

So , we consider the work done on a system gets stored in it in the form of energy. That means , Work(W) = (E) Energy.

Work done by an object is calculated as the product of the force applied on it and the distance it moves in the direction of the force.

=> Work(W) = Force(F) × Displacement (s)

=> W = Fs

=> E = W = Fs
