Confident About Your Physics Knowledge? Watch This!

Physics is ever-surprising. Check this official physics experiment with Newton beads which seem to defy the gravity. Without searching on the Google - try to explain the phenomenon.

I can't see the video right now, but I will take a guessπŸ˜‰, generally gravity can be countered by using like charges (ie electric repulsion ). Maybe beads are charged and have same charge as what is beneath those. (It is just a shot in the dark, tell me if I hit the target 😏 😁 )

In my opinion the explanation is as given in the video. What is seen is a consequence of Newton's Laws of motion. Mainly inertia. The initial length of chain on the outside and the jerk given to start the movement does it. That part of the chain moving up has to keep moving upward. But it is pulled down by the portion of the chain outside the beaker. The shape seen is a dynamic equilibrium between these two opposing forces.
a somewhat similar thing happens with the slinky spring toy elsewhere on CE.
A beautiful demo of Newton's Laws!
