Trevor Jordan · Answer 1

The answer is that, Mass, time, and length are the quantities that would change considering the speed of light as the limit. In Einstein's equations it depends on velocity as a fraction of the speed of light.

we can take example as,

Appeared length = rest length x (1-u ²) ⁽¹/²⁾

in this u is the velocity as a fraction of the speed of light.
