Definition: Energy is the capability to perform work in a given amount of time. It can be divided into three main types: - Kinetic energy - the ability to do work at a constant speed or velocity. - Potential energy - the ability to store energy as kinetic energy when the object is at rest or when it has gained potential energy from being lifted up by an external force. - Thermal energy - the ability to do work at a constant temperature. In other words, the word "energizer" is used as a noun meaning someone who can perform work efficiently. It refers specifically to people who are efficient with their energy resources (e.g. power tools) and can produce more or better results with less effort.
