What does “Work–energy theorem” actually mean in Work, Energy & Power, and why does it matter for NEET?

the net work done on a body equals its change in kinetic energy.

In simple words: the net work done on a body equals its change in kinetic energy. Getting Work–energy theorem clear matters because NEET questions on Work, Energy & Power usually test this idea directly, not just a formula you memorised.

Key point

Work–energy theorem

Common mistake

using only one force's work instead of the net work.

Memory tip

net work > 0 speeds a body up; net work < 0 slows it down.
