PHYS 3210-001: Classical Mechanics

•  video  - Introduction to Lagrangian
• Ball in Curved Tracks

• 1. a simple pendulum made with a ball on a string. 2. another "pendulum" made up of a mass hanging from a lose spring that has negligible length when unstretched. Anchor pivot point firmly to reduce energy loss. 3. A simple rigid circular pendulum (e.g. the chaos pendulum, locked so that it acts like a simple rigid circular pendulum instead) mounted firmly to minimize energy loss.

• Metal ball + long, wide flat board (which I will be rolling the ball down)

• (i) The metal disk with off-center hole that Nikolay made me and a board to put it on that can be inclined. (ii) The spherical chalkboard (black globe you can write on).

• Tom Gallagher teaching ... LCR circuit with 10 and 100 ohm resistors. Use burst mode on Rigol Function Generator (stored as lissajous.RTF), channel 3 = FG, channel 4 = voltage across capacitor (stored as setup 10)

• Hacksaw Blade Resonance

• (i) the Chaos Pendulum. (ii) if you can manage it, a double pendulum with string and balls.

• (i) a basketball or similar sized ball, (ii) a cylinder I can roll on the table, and (iii) the two very large dice.
