OK, i have a final coming up, and i need a little help... i need to know how and why an object moving faster acquires more mass... it doesn't make sense... mass is how much matter somethign has as far as i know, but when you speed up, you acquire more mass? this goes hand in hand with the length contraction i think... the faster you go, the shorter in length you seem, and if that is true, then your mass is going to be the same, and your density will increase... for the mass part, i have a handout that says this "The faster a particle is pushed, the more its mass increases, there by resulting in less and less response to the accelerating force" i don't get this
