Physics Question on Work-energy theorem

The Work-Energy theorem states that the change in

A

Kinetic energy of a particle is equal to the work done on it by the neat force

B

Kinetic energy of a particle is equal to the work done by one of forces acting on it

C

Potential energy of a particle is equal to the work done on it by the net force

D

Potential energy of a particle is equal to the work done by one of forces acting on it

Answer

Kinetic energy of a particle is equal to the work done on it by the neat force

Explanation

Solution

According to work-energy theorem, change in kinetic energy of a particle is equal to the work done on it by the net force.,
i.e. W=FS=12mv2W=F \cdot S=\frac{1}{2} m v^{2}
