In the current Verizon ad featuring LeBron James in a physics lab, there is an instrument displayed prominently in front of each student. What is it?

Some kind of a torsional pendulum. Unless you mean something else.

Thanks. I was wondering if anyone knew the name of the instrument. Much appreciated.

I don't think so.

The student has his book open to: Page 288 Chapter 10 Simple Harmonic Motion and Elasticity
After some googling, I found the book: Physics, By John D. Cutnell, Kenneth W. Johnson

I believe they are studying section 10.2

10.2 SIMPLE HARMONIC MOTION AND THE REFERENCE CIRCLE
...
The model consists of a small ball attached to the top of a rotating turntable. The ball is
moving in uniform circular motion...on a path known as the reference circle.

...​

Figures 10.7 & 10.8 show visually what they are studying.

So it's just a spinning thing.
I'm afraid I don't know any fancy names for something that spins, that isn't shaped like a table.
Actually, there are some tables shaped like that. (Google: very long dining tables)
I'm going to say it's a "turntable".
