According to special relativity, the momentum of a particle increases as its velocity increases, but at speeds near the speed of light, the increase in momentum becomes drastically large. As the particle approaches the speed of light, its momentum approaches infinity, making it impossible to accelerate it further. This relationship between momentum and velocity is given by the formula p=mv/√(1-v^2/c^2), where p is momentum, m is mass, v is velocity, and c is the speed of light. When v approaches c, the denominator of the formula approaches zero, causing the momentum to approach infinity.
