Question

what happened to the density of an object is its speed increases

Answer 1

Postulating Special Relativity, then, for an object with mass and with a dimension in the direction of travel, this dimension will contract, until, if it ever attained the speed of light (SOL), it is zero. SR also predicts that the mass will increase the faster it travels until at SOL would attain infinite mass.

For any normal speed of travel, there would be a calculable contraction and increase of mass but not measurable because the effect would be too tiny.

Hence, density would increase with speed.

Answer 2

Answer:

Hey mate

Explanation:

Density has direct relation with mass. As mass dilation occurs i.e mass increases so the density will also increase.

Hope this helped
