alleryAccording to the work-energy theorem, the net work done on a particle is equal to:
Aits final kinetic energy
Bthe change in its momentum
Cthe change in its kinetic energy
Dthe change in its potential energy
Answer & Solution
Correct answer: C. the change in its kinetic energy
The work-energy theorem states $W_{\text{net}}=K_f-K_i=\Delta K$.
It connects force-based analysis to energy change and is especially useful when tracking the detailed motion is difficult.
