In general relativity, the rest energy of an object is the energy that it has due to its rest mass. The rest energy is the energy of an object that is not due to its motion. It is a measure of an object’s intrinsic energy, also sometimes called its total energy.
The rest energy of an object is related to its mass by E = mc2, where c is the speed of light in a vacuum. The rest energy of an object is also its total energy when it is not moving.
The mass-energy equivalence formula E = mc2 can be used to calculate the rest energy of an object from its mass. For example, the rest energy of a 1 kg object is 9 x 10^16 joules, or about 90 petajoules.
The rest energy of an object can also be calculated from its momentum and speed using the formula E^2 = p^2c^2 + m^2c^4, where p is the momentum of the object and m is its mass.
The rest energy of an object is also its total energy when it is not moving. This is because the kinetic energy of an object is its energy of motion, and the rest energy is the energy of an object that is not due to its motion.
