The total work performed on a particle is equal to the change in its kinetic energy

Options

  1. Aonly if gravitational force alone acts on it
  2. Bin all cases
  3. Conly if the forces acting on it are conservative
  4. Donly if elastic force alone acts on it

Correct answer

B. in all cases

Step-by-step solution

According to the work-energy theorem, the total work done by all the forces acting on a particle is equal to the change in its kinetic energy.

Wnet=ΔKW_{\text{net}} = \Delta K

This theorem is valid for all types of forces, including conservative, non-conservative, internal, and external forces. Therefore, it holds true in all cases.
