2 | Two wheels on an axle: Rotational collisions |
| | |
Main | Two wheels that are mounted on the same (vertical) axis spin separately or together. Data for several cases is presented.In Experiment 2, one wheel spins alone. It is observed that its angular velovity decreases.In Experiment 4, the upper wheel spins, drops onto the lower one and takes it along. More… |
