how does an object gain mass as it accelerates?

Question

where does the mass come from ? does that mean that when I walk, i am actually getting more massive?

I heard that Einstein said that an object gains mass as it acceoerates, or did he mean that only if the object goes at the speed of light?

Answer 1

It's not that it gains mass...it gains inertia and it gets harder and harder to acellerate. In this case mass and inertia work the same way.
The true amount of matter that makes up the object (mass)doesn't increase. It just gets harder and harder to move any faster.

Answer 2

i think of you're questioning of relativity right here. In particular relativity the mass will enhance with the fee no longer with acceleration- regardless of the actuality that ,of direction the acceleration is the element that will enhance the fee. The mass easily will enhance with any enhance in capability . The capability defined via speed is kinetic capability and it relatively is a million/2mv x v --(i'm sorry i do no longer understand the thank you to do exponents on right here) the upward push in mass simply by kinetic capability is discovered from E=mc x c for this reason Mass enhance =E/(c x c) SO mass = a million/2m(v x v)/(c x c) c = 30000000000cms/sec so c(squared) is an relatively vast no. this suggests that any mass enhance at "common" velocities is relatively very small certainly and can regularly be skipped over. of direction ordinary debris can trip at very extreme velocities and enhance their mass heavily. notice that throughout the time of particular Relativity an merchandise's speed relies upon on the fee of the observer-- So the mass of an merchandise differences based how briskly "you" are traveling the region usually relativity is possibly too complicated for this communicate board

Answer 3

dats bcos einstien proposed :::
mass(motion)=mass(original)/root(1-v2/c2)
yes when u walk u gt more massive but u cn neglect d change .
this relation comes into play when the particle is small or when ur at very high speed

Answer 4

It does not.
