Have you ever seen a square? It's 2-D. If you can get a square to role, let me know. You're thinking CUBE. Here's an experiment. Take a Rubix cube (one of the cubes with all the little coloured squares) and a ball of some sort. Now take them both, and roll them. See which one makes it the farthest?
Squares have flat edges (faces) with corners (vertices), therefore as it "rolls" so to speak, each face comes in contact with the surface it's rolling on, and slows it down. The ball is one continuous face, so it will roll smoothly.
if you push one hard enough it will, but it wont go very far. generally things with edges wont roll, a circle rolls because it has no edges, and thus nothing to stop it but gravity or something in the way
Just checking.. believe it or not some people have no idea hahaha. but yes it roles somewhat, not nearly as well though read the last paragraph.. haha its better
when u try and roll a cube it has to convert alot of its forward momentum into angular momentum.
and try useing google it took me 15 secconds to find that out.
Because they have edges. They kinda roll, though. Did you know the first wheel was square?
Hahaha I'm not handicapped, I know what a Rubix Cube is! That still means that it roles!
Squares don't roll because they have edges that stop it.
because their lame :)
