Slope of energy-time graph is equal to:
Correct answer: C. Power
- A. Acceleration
- B. Momentum
- C. Power
- D. Work
Explanation
Slope d(E)/dt is the rate of change of energy with time, which by definition is power. Therefore energy‑time graph slope represents power.

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.
