Question:
Will a Newton's cradle run longer in time from start to finish, in a vacuum chamber? Due to no air resistance and energy lost in the form of sound when the balls collide.


Replies:
Yes.

Tim Mooney


Chris,

Just as a Newton's cradle runs for less time in water, I expect it would run quite a bit longer in a vacuum. Still, it would not run forever. Some energy can work its way through the strings into the support and then into the table.
