Special relativity only handles the part where mass depends on the speed of the object.... and also gave us E=mc^2, where this m= m0/sqrt(1-v^2/c^2), and m0 is the mass at rest, v is the mass' velocity, c is the sped of light.
The general relativity is the one that shows space-time bending due to the gravitational field.
Cheers; I always get those two mixed up. Relatively speaking, that is.

which theory of relativity?
Indeed - there's the famous two of Einstein's, Special and General, and then there's Galileo's Principle of Relativity, from which Einstein's Special Theory was devised. Galileo's Principle - also known as Galilean Invariance - states, basically, that to an observer inside a sealed vessel (ship. aircraft, spacecraft etc) with no windows or some other way of seeing outside, there is no way of knowing whether the vessel is moving or at rest, relative to its surroundings.
There is actually a fine example of Galileo's Principle in, of all things, the James Bond film The Man With The Golden Gun. The Bond girl du jour, Mary Goodnight (Britt Ekland) is locked in the boot - trunk if you like - of the villainous assassin Scaramanga's (Christopher Lee) car, which at some point in the obligatory car chase enters a hangar and comes out fitted with wings and then takes off like an aeroplane. Goodnight is in radio contact with Bond throughout and once the car has taken flight, she radioes back that she thinks they've stopped and decides to open the lid to climb out - whereupon she realises just where she is. In other words, she has up to that point had no way of determining whether the car is moving or not; since the car is no longer in contact with the road and there are no bumps being transmitted through the suspension, all is as smooth as it would be if the car was parked.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
