2. Mass and energy Einstein’s theory E = m c 2 Energy corresponding to one electron: 1 kg m 2 S -2 = 1 joule Because:

3. Mass and energy mass of one carbon atom = Example 1-7. Calculate the energy equivalent of 1 atomic mass unit (amu). Avogadro's number = 6.022045 ×10 23 carbon has a mass number of 12, it contains 12 amu Hence, the conversion of 1 amu to energy

4. two important mass-to-energy conversion factors :

5. Mass and velocity m 0, the rest mass 1/10 the velocity of light, increase in mass of 0.5% 98% of light (v/c ＝ 0.98), 5 times of the rest mass
