    Work: When a force acts on an object and the object shows displacement, the force has done work on the object.
    Two conditions need to be satisfied for work to be done:
    (i) A force should act on object
    (a) The object must be displaced
    Work = Force x Displacement Unit of workdone = Joule = Newton x metre 1 Joule work is said to be done when 1 Newton force is applied on an object and it shows the displacement by 1 meter.

    Energy
    The capacity of a body to do work is called the energy of the body.
    Unit of energy = Joules 1KJ = 1000 J

    Forms of Energy: The various forms of energy are potential energy, kinetic energy, heat energy, chemical energy, electrical energy and light energy.

    2Thank You
