Question

Can anyone explain me The work-energy theorem for a variable force from the chapter WORK, ENERGY AND POWER class 11..


Plz fast..tmrw is my exam

Answer 1

the theorem states that whenever a work is done on an object it moves. from some point A to B then that work done on that object. by all the forces is going to change its kinetic energy.

Answer 2

Answer:

Theorem of work energy

Explanation:

Net work done on an object equals the objects change in kinetic energy . Also called the work energy principle.

Equation:-

W net = K - Ko

= ◇ K

W net = net work

K = final kinetic energy

Ko = initial kinetic energy

◇K = change in kinetic energy
