Ball movements

[simontt]

Hi all,

Can someone tell me why a ball will float around in warm weather? We don't get much of it here in England, so when we do get it, the ball floating all over the place can really throw my game out!

Also, if the ball floats around in warm weather, what happens in cold conditions?

Heat rises..... just saying

Someone can correct me if I'm wrong but,

When it's hot, the air molecules move around faster (well, they vibrate more), thus creating a larger force on the underside of the ball and forcing it to float a bit more.

That's my theory at least.

they vibrate more as they get more energy (ge hotter) . they dont really move from a to b. as molecules vibrate more or get warmer or receive energy( one is the result of the other two) they get further apart ( i think this is to do with the molecular bond as far as i remember) . so asa they are further away from each other air ultimately becomes lighter and rises which in turn lifts the ball
