The international (SI) unit is the Joule. Several other units are used worldwide, in specific contexts, for example the BTU, the eV (electron-volt), or the Ah (ampere-hour, for measuring battery capacity).
kJ
by adding the objects kinetic energy and potential energy
Energy is measured in Joules for all applications. However in nutrition calories are also used. There is a fixed relation, 1 calorie = 4.2 Joules.
The SI unit of energy is the joule (J) Energy levels in atoms are sometimes measured in electron-volts (eV)
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
If you refer to the unit, the international unit for energy is the joule; the symbol is "J".
The unit used to measure the energy of an electromagnetic wave is called a photon.
The standard unit of measure for energy is the joule (J). This unit is used to measure all forms of energy, including kinetic, potential, thermal, and electromagnetic energy.
The joule.
Calorie is the unit used to express chemical energy in food.
The unit used to measure chemical energy is the joule (J) or the calorie (cal).
The unit used to measure thermal energy besides joules is the calorie. It is commonly used to quantify the energy content in food and beverages.
work and energy +++ The Joule (J) is the unit of energy, alone, not of work. The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
A kilocalorie is not a measure of weight. It is a measure of energy
Energy of heat = Joules (J)
The unit used to measure kinetic energy is the joule (J).
