Explanation
Energy is the power or ability to do work, move, or be active. People get energy from food, sleep, and exercise. For example, a child has lots of energy to play all day. Energy can also mean electricity or fuel that powers machines. Scientists study energy to understand how it moves, changes, and is used. In feelings, “energy” can describe being lively, active, or full of life. Without energy, work, movement, or activity is difficult or impossible.
