Newton’s Cradle is a corporate toy most of us wish to have on our work tables. This swinging ball setup relieves stress in some and inspires creativity in others, but for the majority of people, it is little more than a fascinating distraction. ...

Science Advisor Gold Member 2024 Award 9,675 11,179 Leoragon said: So in F = ma, the units are: kg, m/s2, and Newtons? To clarify what you said, my examples are the same. No difference? yes so F (Force in Newtons) = m (mass in kg) x a (acceleration in m/s2) so ...
(according to Oxford: "extreme or alarming importance; seriousness") or gravitas ("dignity, seriousness or solemnity of manner") take on additional significance. That said, when someone refers to the "gravity of a situation" a physicist might still need clarification: Do they mean in ...
There are newer, more sensitive tools that measure grip in newtons. This makes it easier to record small changes between trials. The authors suggest frequent recalibration of instruments to ensure their accuracy. The mean value from three grip strength recordings should be used as suggested by the...

If you have an empty bag, continuing this pattern would mean the probability of never drawing the same ball more than once is 0!/0^0. But since you have no balls to extract in the first place, the probability of never drawing any ball more than once is clearly 100%! Which means 0!
