Question

The total work done on a particle is equal to the change in its kinetic energy. This is applicable

• A. always
• B. only if the conservative forces are acting on it
• C. only in inertial frames
• D. only when pseudo forces are absent

Answer 1

The correct option is A always

Work energy theorem:
The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.
$W=\Delta K$ is always applicable.
