Instantaneous energy can be measured by calculating the power of a system at a specific moment. This can be done by measuring the rate of energy transfer or by using a power meter. The unit of measurement for instantaneous energy is typically in watts or joules per second.

The unit of measurement for electromagnetic energy is the joule (J).
Instantaneous displacement is the distance an object has moved from a reference point at a specific point in time. It is often measured as a vector quantity, indicating both the magnitude of the distance and the direction in which the object has moved.
Instantaneous speed is the speed of an object at a specific moment in time, while speed refers to the average rate at which an object covers distance over a period of time. Instantaneous speed gives the speed at a precise instant, whereas speed provides an overall measure of how fast an object is moving.
The energy given off by burning fossil fuels can be measured in joules or kilojoules. This measurement quantifies the amount of heat or energy produced during the combustion process. It helps in understanding the efficiency and environmental impact of using fossil fuels for energy generation.
Potential energy is typically measured in joules (J) in the International System of Units (SI). It can also be measured in electronvolts (eV) in the field of particle physics.
