# Einstein’s Mass-Energy Equivalence and Nuclear Fusion Quizlet

relativistic momentum

as an object approaches the speed of light its momentum approaches infinity

rest mass

the mass of an object as measured in a frame of reference where the object is at rest

relativistic mass

increased mass of an object moving at speeds approaching the speed of light

total energy

the sum of an object’s kinetic energy and mass-energy

nuclear fusion

a nuclear reaction in which light atomic nuclei fuse to form a heavier nucleus with the release of energy

general relativity

the leading theory that explains gravity on the large scale as a geometric property of spacetime

photon

a particle of electromagnetic radiation with no rest mass that carries energy

proton-proton chain

nuclear reaction that produces sun’s energy

synchrotron

a particle accelerator that produces intense electromagnetic radiation and relies on the principles of relativity for its correct design and operation

GPS

a system that determines the precise position of an object on Earth through a series of satellites, tracking stations, and receivers and relies on the principles of relativity for its correct design and operation
