Which term refers to the power and ability to be active?

Energy is the term that refers specifically to the power and ability to be active. It encompasses different forms, including kinetic energy (the energy of movement) and potential energy (stored energy based on an object's position or state). The concept of energy is fundamental in science, as it is a measure of the capacity to do work or cause change. In various contexts, energy is vital for physical activities, chemical reactions, and biological processes.

The other terms, while related to concepts of power and activity, do not encapsulate the idea of active capability as directly as energy does. Strength typically refers to the physical ability to exert force or withstand pressure but does not specifically address the active power aspect. Force is a vector quantity related to an interaction that causes an object to accelerate, but it is not synonymous with the overall ability or power to be active on its own. Potential usually refers to the capacity for something to develop further or become active but does not imply current activity or energy in motion.
