Question

32. Work done by a force is given by W = F. S where F
is the force and is the displacement. Show that:
(a) Work done is also equal to change in K.E.
(b) Work done is also equal to change in potential
energy using this expression.​

Answer 1

Answer:

The Work-Energy Theorem

The work done by a force →F which displaces the point of application through →s while in action is given by W=→F. →s. . If the force and the displacement are parallel this reduces to the algebraic product Fs .

Explanation:

The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.

Work is the measurement of the force on an object that overcomes a resistive force (such as friction or gravity) times the distance the object is moved. ... When you are doing work against continuous resistive forces, such as gravity or spring tension, work done equals the change in potential energy of the object.
