| Question | Answer |
| What did Einstein explain in his theory of special relativity? | How an object dissipating energy will loose some mass and as a result an object gaining energy will gain mass |
| What is the mass-energy equivalence equation? | E=mc^2 |
| What does 1 Mev equal in J and Kg? | 1.6 x 10^-13 j 1.77 x 10^-30 Kg |
| What does 1 u equal in Mev? | 931.3 Mev (the mass of 1/12 of a carbon 12 atom) |
| What is the effect of mass-energy equivalence on a macroscopic scale? | Negligable |
| When are the effects of mass-energy equivalence more significant? | On nuclear levels such as Nuclear decay, Nuclear fusion and Nuclear fission |
| What is the energy involved in an alpha particle decay? | Due to conservation of momentum, the nucleus will recoil and gain a small amount of kinetic energy. The alpha particle always has the same energy |
| What is the energy involved in beta decay? | The energy is divided between the beta particle and neutrino in varying quantities. The nucleus will recoil slightly taking a very small amount of energy |
| What is the energy involved in Electron capture? | A neutrino is emitted carrying the entire amount of energy. The nucleus does not recoil because the neutrino is massless |
