If we assume the marble is rolling instead of sliding then there necessarily must be friction between the bowl and the marble.

What is the restoring force and what role does the force you apply play in the simple harmonic motion shm of the marble.
Physics stack exchange is a question and answer site for active researchers academics and students of physics.
A fun physics activity from science buddies.
Start the marble rolling tangentially in the bowl to obtain an orbit then observe the effects of conservation of angular momentum.
We can make it roll back and forth just as a marble would in a real bowl.
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.
When the jell o is set in each cup place a marble on the surface of the jell o in the center of the cup.
The friction causes a torque which is not included in the op s computation.
To demonstrate orbits in a gravitational potential well.
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.
In our atomic ion experiments we can make an atomic marble.
Get a feel for the force required to maintain this periodic motion.
