1. **Power** is a general term that can refer to various forms of strength or capability. In physics, it commonly denotes the rate at which work is done or energy is transferred. Colloquially, power can also describe a person's influence or control over others.

- Example: "Human beings require energy to perform physical tasks and maintain body heat."
3. **Strength** refers to the physical power or force possessed by an individual or object. It is often associated with the ability to withstand force or to exert force.
- Example: "She lacks the strength to lift the heavy box."
