Question

define work energy theorem

Answer in long please
​

Answer 1

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

Key Takeaways

The work W done by the net force on a particle equals the change in the particle's kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2 .

The work-energy theorem can be derived from Newton's second law.

Work transfers energy from one place to another or one form to another.
