if we make a graph of speed(as .1c/.5c/.6c/.9c) vs mass graph....using the law of momentum conservation..why dose the mass increase??????(c=speed of light)

Dear Praroop,

According to relativity, as speed increases, energy increases, which in turn increases INERTIA, which in turn increases mass, because energy and mass/inertia are two sides of the same coin.
