Unit of measurement of energy
Energy is a physical quantity that is used to describe the ability of a system to do work. It is a scalar quantity that is measured in units of Joule (J).
Joule as a unit of energy
Joule is named after the English physicist James Prescott Joule. It is defined as the amount of work done when a force of one newton is applied over a distance of one meter. In other words, it is the energy transferred by a force of one newton acting through a distance of one meter.
Other units of energy
Although Joule is the most commonly used unit of energy, there are other units of energy as well. Some of them are:
- Calorie (cal): It is the amount of energy required to raise the temperature of one gram of water by one degree Celsius.
- Kilowatt-hour (kWh): It is a unit of energy equal to the energy consumed by a 1,000-watt appliance over a period of one hour.
- Electronvolt (eV): It is the amount of energy gained by an electron when it moves through a potential difference of one volt.
Conclusion
In conclusion, the unit of measurement of energy is Joule (J). It is the amount of work done when a force of one newton is applied over a distance of one meter. Other units of energy include calorie, kilowatt-hour, and electronvolt.
