when a junked car is crush into a compact cube, does its mass change? its volume? its weight?

Question

all about in physics

Answer 1

Mass and weight stay the same, volume decreases.

Answer 2

Yes, all three will change in some amounts. Its volume will change, but its essential weight and mass won't.

The slight changes in weight and mass will occur while crushing, a good bit of the air inside the vehicle will be forced out. The object's ability to hold air is also reduced. Depending on the size and dimensions of the original vehicle, and how much air it originally could encompass, the mass and weight corresponding with that air will be reduced. This will be a minute, but measurable change.

Its volume will be the most noticeable reduction. A cargo van will have more noticeable effects on it than a corvette, because of the open space each vehicle's design encompasses. This change will be the most easily measured.

Answer 3

Assuming none of the pieces fall of, nothing will change.

Instead of the vehicle being spacious, all the parts are pushed together into a seemingly solid piece, why should anything change? Make a sculpture out of tin foil, then crush it into a little ball. If you weigh it before and after, the weight will not have changed. Unless you crush something so powerfully, you can reduce the amount of space between molecules. But I do not believe this is the case.

Answer 4

The volume changes, but unless it crushes out some gas or engine fluids, the mass and weight won't change.

Answer 5

Volume changes. Others stay the same.

Answer 6

Only the volume does.

Answer 7

Its mass and weight stay the same, the volume decreases and the density increases.

Answer 8

only the volume changes

Answer 9

just it's volume. In the sense that It doesn't take up as much space.

Answer 10

Nothing should change but its volume and density.
