The total work performed on a particle is equal to the change in its kinetic energy
Options
- Aonly if gravitational force alone acts on it
- Bin all cases
- Conly if the forces acting on it are conservative
- 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.
This theorem is valid for all types of forces, including conservative, non-conservative, internal, and external forces. Therefore, it holds true in all cases.
