When an object approaches the speed of light dose the mass increase or decrease?

Answer 1

As it moves through my laboratory, I see its clock run slow, I see its thickness in the direction

of motion shrink, and I see its mass greater than it was when the object stood here with me.

Someone riding on the object and watching me as it sails through my laboratory will see my

clock run slow, my thickness in the direction of motion shrink, and my mass greater than

it was when he stood here with me.

The faster the object is sailing through my laboratory, the more pronounced these effects will be

for both of us. If it's only creeping along at, say, 10 million miles per hour, then it's only moving

at about 0.1% of the speed of light, and the effects are hardly noticeable.

Answer 2

hmm honestly while an object flows like the speed of the sound then surly that will get so much of tension and friction on it, if it has that capability to withstand that much of the force and resists that also could be remain the same shape and size then that won't get any decrease in its mass but in that case against then surly u know it must loose its layers out side poses around it and also get smaller from its original size

Answer 3

As soon as any object moves, no matter how fast or slow, its mass increases.

The faster it moves, the greater its mass becomes. The reason that wasn't

known for so long is that the effect isn't noticeable to us at any speed where

we have daily experience.

Regardless of how small its mass may have been when it wasn't moving, any

object approaches infinite mass as its speed approaches the speed of light.

Answer 4

The mass of anything increases when the thing moves. The faster it moves, the more

its mass increases. At any speed that we're likely to encounter in everyday life, the

increase is so small that we don't notice it. When the speed becomes a significant

fraction of the speed of light, the increase in mass also becomes significant, and it

rises faster with further increases in speed. Theory predicts . .. and thousands of

experiments confirm ... that as speed approaches the speed of light, the mass becomes

infinite, no matter how tiny it was before it started moving.

Answer 5

The particles mass increases without bound as it approaches c, the speed of light.

Answer 6

The mass will approach infinity in this case.

Answer 7

Yes.
