Power is often confused with energy because both are fundamental concepts in physics that relate to the performance and behavior of systems, but they describe different aspects. Energy is the capacity to do work or produce change, while power is the rate at which that work is done or energy is transferred over time.

To clarify, energy can exist in various forms (such as kinetic, potential, thermal, etc.) and is measured in joules. Power, measured in watts, quantifies how quickly energy is used or transferred. For instance, a light bulb may consume a certain number of joules of energy per second, indicating its power. This distinction leads to the common confusion between the two, as both are often used when discussing the efficiency and performance of machines and processes.

By understanding that energy refers to a total quantity and power refers to that quantity being utilized or transformed over a specific time, one can better distinguish between them. This fundamental difference is crucial for solving many physics problems related to mechanical comprehension.
