What unit is energy measured in, according to the energy equation?

Energy is measured in joules, which is a standard unit of measurement in the International System of Units (SI). The energy equation often refers to the work-energy principle or can be discussed in various contexts such as thermodynamics or physics. When energy is involved in a system's dynamics, it is often associated with work done or energy transferred.

Joules per second is the definition of a watt, which is the unit of power. Power is the rate at which energy is transferred or converted, essentially describing how quickly energy is used or generated. Therefore, while joules per second indicates how power relates to energy conversion, energy itself is fundamentally measured in joules.

The mention of volts and newtons pertains to different dimensions in physics: volts measure electric potential, while newtons measure force. Neither is a unit for energy. While watts can be expressed in terms of joules per second, the most direct answer specifically regarding the measurement of energy aligns with the joule as the unit of energy itself. Thus, identifying energy directly leads to understanding its fundamental measurement as the unit of joules.
