yes yes its me with another stupid post.

I was thinking, if you had a spring attached to the ground, which would compress very tightly, and you had a ball of a certain weight on the spring, if you released the spring and the ball shot up in the air, if it was the correct weight and the spring was the correct tightness could it fall back on the spring and bounce back up to a height where it would constantly bounce from the spring? Ive explained it terribly.

No, each time the ball bounced it would shed energy.

If you can solve the problems surrounding a perpetual motion machine then you will become a very rich and famous young man.


I don't have high hopes of that however.

Not really sure if this is meant to be trolling or not, but anyway:

Only if everything worked at 100% efficiency. I.e. there was no atmosphere (no air resistance), no energy loss in the forms of heat (most common), or noise (try dropping something, onto something else, it makes a noise right? That noise is lost energy that will prevent the ball rising to the same height) etc etc.
 
Unfortunately due to friction, aka air particles, it would not bounce the same height twice and as such it will eventually come to a point where it does not bounce at all.

Thats my late night brainage thinking on this o,0

how about if it was super lubed up?

You'd need a friction-free lubricant (as in 100% friction free (doens't exist)) on the spring, and the ball (to stop air resistance). And even then it would only bounce back the same height it did the first time you released it.
 
Now all we need is the OP to claim he's a girl to avoid ridicule that is the opening post, then spend 2 hrs posting pictures that don't actually prove said sex whilst everyone debates the effectiveness of tineye until it all gets out of hand and someone posts a tranny in a bikini and the thread ends.

Oh, wait..
 
damnit.. Ok, another one for you all.

If you had a block of ice at -50 degrees celcius and you popped it in a bucket which was the same amount of water as the ice but it was at 50 degrees celcius would the water freeze or melt?
