In an inertia experiment using equipment very similar to the link below, I determined the following:
Trial with two 100 g masses near the ends of the rotating apparatus (larger moment arm):
- Final translational kinetic energy: 5.73 * 10^(-4) J
- Final rotational kinetic energy: 0.638 J
Trial with two 100 g masses closer in on the rotating apparatus (smaller moment arm):
- Final translational kinetic energy: 1.27 * 10^(-3) J
- Final rotational kinetic energy: 0.638 J
The final rotational kinetic energy is much larger than the final translational kinetic energy. Why is that the case?
