能量
How to Understand
能量 (néng liàng) is the Chinese word for 'energy,' referring to the capacity to do work or the power that drives physical or mental activity. It can also refer to vitality or the force behind a person's actions.
The character 能 (néng) originally meant 'to be able' or 'capacity,' and it later came to represent the concept of energy or power. The character 量 (liàng) means 'quantity' or 'measure.' Together, they form a term that conveys the idea of measurable power or strength.
能量 is commonly used in both scientific and everyday contexts. In physics, it refers to kinetic or potential energy. In daily life, it can describe someone's enthusiasm or physical stamina. The phrase 精力充沛 (jīnglì chōngpèi) means 'full of energy' and is often used to describe a lively or energetic person.
