- Newton's cradle 6 answers
For "Sinterklaas" (Dutch holiday) I got a Newton's cradle. I understand the basics of it, but a couple things bother me.
If I drop one ball, one bounces off. If I drop two, two bounce off. Why, if I drop one, don't two bounce off at half the speed? And the other way around, if I drop two, why doesn't one bounce off at twice the speed?
What would happen if I'd stick two together, and drop one on the other side? Would the two then go with half the speed? Is this the same as a ball that's twice as heavy as the others?
And for bonus points: would there be a way to make one ball shoot off at a higher speed as whatever I drop?
If possible, please eli5.
