I have a Newton's cradle on my book case, I used it to power Windows 2000 now it just sits there.

Hate to be finicky, But this does not prove or demonstrate newtons 3rd law. This device, known as a "newtons cradle" illustrates the law of "conservation of momentum", which states:

Quote:
For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained by object 2.
While its sure that Newton knew of the law conservation of momentum, it is not classically described as one of his 3 laws.

A better illustration of Newtons 3rd law is the recoil you feel when you fire a gun.

P.S. Forgive me, but inside of every engineer is a teacher dying to get out.

I'm no physics major but it would seem that even if the law of conservation of momentum is not in itself the 3rd law, it is most inextricably linked.

Trust me--I have no clue--I just a poor mid west dirt scratcher!!

But I do feel honored to know more (maybe) about Newtons Law. Not sure what I will do with it. But honored!!

Law of Conservation of Energy. Ergo.......That all energy, without exception, is wasted. It's the reason a Perpetual Motion machine is impossible.
