The demonstration begins with a torsional balance consisting of a dumbbell on a wire. Cavendish’s famous experiment to measure the gravitational constant is described using the apparatus as an illustration. An experiment is then done. The equilibrium location of a laser dot is marked on a distant whiteboard. Two large masses are then placed near the dumbbell masses such that the attractive grav...

Angle that maximizes the range of projectile

Unlisted

projectile motion is horizontal projection

A dumbbell is suspended from its center by a wire, and can undergo rotational oscillations due to the twisting of the wire. The oscillations are observed to be very weakly damped. The period is measured to be independent of the amplitude, including very small amplitudes that are seen by reflecting a laser beam off an attached mirror to a distant whiteboard. Hitting the table by hand causes high...

Understanding the Dot Product and Conservation of Energy

Two identical billiard-ball pendulums touch side-by-side in equilibrium. The balls are pulled aside a small amount in the transverse direction, and one ball is given a velocity directly toward the other ball, which is initially at rest. Repeated collisions occur, where one ball undergoes uniform circular motion (conical pendulum) over a half-cycle, and the other ball undergoes simple harmonic m...

From Dr. Denardo, "I forgot to state something at 13:04 minutes. The drive is SLOWLY increased so that the RESPONSE IS IN THE STEADY STATE; otherwise, transients are introduced." Driven damped torsional oscillator: In the steady state, the maximum response of a driven oscillator occurs on resonance, where the drive frequency equals the natural frequency. The velocity is in-phase with the force,...
