Question What is that"perpetual motion machine" thing that sits on a desk, with 5 or 6 balls hanging by threads called?
It sits on a desk usually, with 5 or 6 balls hanging by a thread, and you pick the one up on one side, it smacks into the other 5, and the 4 in the middle don't move... only the one on the far side goes flying... then it bounces back, and again the middle ones don't move, only the first one you touched. What is that thing called??

Best Answer Newton's pendulum or Newton's cradle

Question Is God's earth a perpetual motion ball of water of varying biological life in a contained system generator...?
. Perpetual motion machines are machines that are supposed to disobey one of the laws of thermodynamics.......basically they create energy from nothing. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism. How is it that the field of gravity must be just right to contain atmosphere... block space radiations ...and control the speed at which the surface of our earth coincides with the speed of both inner core and outer core ....? The chaotic nature of a dynamo itself is so organized that it dumbfounds empirical sciences all the time. Is the earth heating up or cooling off at the center...? .

Best Answer No, lol

Question If I made a ball roll endlessly in a closed loop, would that be considered a perpetual motion machine?
Not free energy obviously, but perpetual motion?

Best Answer Only if the ball really continues rolling indefinitetly, without ANY additional energy from external sources, and does not lose any energy.
