Gravity does not effect speed of light ,so velocity is constant. Even if it effect the effect is negligible. So in short answer is 3*108ms-1

### What are the characteristic of light at zero gravity?

When there's no gravity, light just travels in one direction at the speed of light. Gravity bends the direction at which light travels.

### What effects the speed of a object?

Speed is relative to the speed of light and gravity. So gravity could effect speed.

### Does gravity travel at speed of light?

Gravity wave do, so yes.

### When will a body have zero speed?

yes it is possible to get a zero speed 4 a body but nly whn the universe come to a stand still n gravity will b zero...........................

No.

### What is the speed of gravity?

C To expound, gravity and light travel at the same speed. * It is a fundamental fact of nature that nothing can travel faster than light, but matter slows light while gravity is not slowed or screened by anything. So light and gravity only travel at the same speed in the vacuum of space away from any mass.

### Light from a star travels from earth in a straight line at a constant speed of 300000 kilometers per second What is the acceleration of the light?

The speed of light is a constant, so the acceleration is zero. However, light IS affected by gravity, and gravity causes an acceleration. How does this balance? The light moves at the same speed - the speed of light, abbreviated "c" - but loses or gains energy as the light moves toward or away from the gravity source. In gaining energy (without speeding up!) the frequency of the light is increased and the wavelength of the light (or any electromagnetic energy) is decreased, In losing energy, the wavelength is increased and the wavelength decreased. This could be a trick question, of course. Light from a star wouldn't be travelling from earth, unless we are talking about reflected light, which would not be particularly intense, but it is not out of the question.

### What can travel at light speed?

Anything with zero rest-mass. This means photons (quanta of light), gluons (the mediators of the strong nuclear force) and gravitons (the mediators of gravity, if they exist). All other particles have non-zero rest mass and can only travel at sub-light speeds. There has been some mention in the news of neutrinos exceeding light speed. However, those results are still being debated.

zero

### How much zero gravity is there in space?

Zero! that's why it is called zero gravity!

### Why is the speed of light important in physics?

The speed of light seems to be a speed limit in the Universe - it isn't possible to transport matter, energy, or information faster than that. Others think that gravity travels faster; Einstein created a universe with an infinate speed of gravity -- it's in the geometry.

### How fast is an electron?

From zero to nearly the speed of light. It depends on conditions.
