Physics Course/Relativity

Relativity
According to Newton Mass of any moving object remains the same regardless of speed travel. According to Einstein any moving object has Mass changes with speed travel

Change in Mass relate to speed travels
Speed of light is alsway constant, v = C. When matter moves at speed of light, matter no longer has mass. Observed fron Plank in experiment with Black Body Radiation
 * $$m = 0$$ when $$v = C$$

All matter moves at speed less than speed of light has a mass of mo
 * $$m = m_o$$ when $$v < C$$

Therefore for any matter moving at speed less than speed of light but not equal to the speed of light
 * $$m = m_o (1 + \frac{v}{C})$$

Wave length of a Momentum
Any momentum travels at speed of light C carries quantum energy $$E = h \frac{C}{\lambda}$$ will have a wavelength
 * $$\lambda = \frac{h}{p} = \frac{h}{C} \frac{1}{m}$$

Which can be easily proved
 * $$pC = h \frac{C}{\lambda}$$
 * $$\lambda = \frac{h}{p} = \frac{h}{C} \frac{1}{m}$$
