the flywheel light enough to drive by breath for hands-on reciprocating-engine study

measuring period under different loads to isolate mass from weight

sized for low-current circuit work below the 1A range where finer resolution matters more than full-scale capacity

Designed for liquid-fill Snell's-law work at smaller scale

One-inch brass ball that threads onto a pendulum string as a heavier metal counterpart to aluminum or steel balls in mass-dependent periodic-motion investigations
