LeBron James' Verizon science experiment

  1. Jul 10, 2016 #1
    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".
