Marble in a bowl physics.
Find a bowl or basin that is shaped like a hemisphere on the inside.
By science buddies on july 12 2012.
Place a marble inside the bowl and tilt the bowl periodically so the marble rolls from the bottom of the bowl to equally high points on the sides of the bowl.
The friction causes a torque which is not included in the op s computation.
What is the restoring force and what role does the force you apply play in the simple harmonic motion shm of the marble.
In our atomic ion experiments we can make an atomic marble.
If one calculates.
Shm and the marble.
We can make it roll back and forth just as a marble would in a real bowl.
Start the marble rolling tangentially in the bowl to obtain an orbit then observe the effects of conservation of angular momentum.
Physics stack exchange is a question and answer site for active researchers academics and students of physics.

Marble in glass bowl purpose.
And at some instance of time then the atom will be on the right side of the bowl and a little bit later on the left side of the bowl.
A fun physics activity from science buddies.
Marble and glass bowl.
To demonstrate orbits in a gravitational potential well.
