Thus an object's kinetic energy is defined mathematically by the following equation….

in the limit of small speed here, most terms are very small.
The Fermi National Accelerator Laboratory, near Batavia, Illinois, was a subatomic particle collider that accelerated protons and antiprotons to attain energies up to 1 Tev (a trillion electronvolts).

Physics of Energy I - 4 Understanding the physics of energy means learning about two sorts of things. equivalence must now be taken into account, for example, in the by the familiar expressionThe corresponding relativistic expression for kinetic energy can Rest energy is large because the speed of light c is a large number and c 2 is a very large number, so that mc 2 is huge for any macroscopic mass.

For this reason, invariant mass is in general not an additive quantity (although there are a few rare situations where it may be, as is the case when massive particles in a system without potential or kinetic energy can be added to a total mass). The invariant mass, rest mass, intrinsic mass, proper mass, or in the case of bound systems simply mass, is the portion of the total mass of an object or system of objects that is independent of the overall motion of the system.
