Which physical quantity represents the rate of doing work or the rate of transfer of energy?

💡 Solution & Explanation

Power is scientifically defined as the rate of doing work or the rate at which energy is transferred, measured in Watts or Joules per second. Options like momentum, energy, and force represent different physical phenomena such as mass in motion, capacity to do work, or a push and pull, rather than the time rate of energy transfer. Understanding power is essential for analyzing mechanical and electrical systems in physics.
