According to work-energy principle work done on body will equal to change its
Correct answer: A. K.E. only
- A. K.E. only
- B. P.E. only
- C. K.E. and P.E. both
- D. All may be correct
Explanation
The work-energy theorem states that the net work equals change in kinetic energy. Work may convert between energies, but net work directly relates to ΔK.E., so option A is the precise statement.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
