when the particle moves with the speed of light,the mass of the particle increases to infinity.... this is as per Einstein's theory of relativity....n its true.... some people say the mass decreases to zero when the particle travels with the speed of light....they are "INSANE"
According to Einstein's special theory of relativity, mass can be converted into energy, and is given by the relation E=mc2, where c is the velocity of light. From the question, the object thus will be converted into energy
Your question is somewhat senseless because it is impossible for an electron to travel at the speed of light as it has mass.
It moves at a slower speed!
If speed approaches the speed of light, the mass of any object will increase. This is not just theory; it is observed on a daily basis. Not with spaceships, of course; the technology is not ready yet - but with subatomic particles in accelerators.
As long as the light remains in the motor oil, nothing happens to its speed.
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
The ray bends away from the "normal" a line that runs perpendicular through the boundary of the two materials.
When any object with mass moves, no matter at what speed, its mass increases. The faster it moves, the faster its mass increases. And the closer to the speed of light it moves, the closer to infinity its mass grows.
An object such as a train simply CANNOT travel at the speed of light. You can investigate what happens when it moves close to the speed of light.

The speed increases.
It isn't quite clear what you mean with "direct speed". Any time an object moves, it has speed.
It increases in order to conserve angular momentum.
An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
The speed changes. (and sometimes the angle.)
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
No material object ever moves at the speed of light. The Earth's speed in its solar orbit ... relative to a foolish astronomer sitting on the sun ... is about 29.78 kilometers per second. That's about 0.0001 of the speed of light.
