Question

Explain work energy theorem for variable force​

Answer 1

Work is said to be done when an acting force displaces a particle. If there is no displacement, there is no work done. You might get tired if you keep standing for a long time, but according to Physics, you have done zero work.

Thus, work is a result of force and the resulting displacement. Now, we already know that all moving objects have kinetic energy. So, there must be a relation between Work and kinetic energy. This relation between the kinetic energy of an object and workdone is called “Work-Energy Theorem”.

Answer 2

HEYY MATE!

The work energy theorem states that the change in kinetic energy of a body is equal to the work done by net force acting on it.

I don't know much abt it

hope to see u on insta
