04:33 Inertia – Mass – Friction – Amazing Physics! I discovered that a large ball bearing will spin for a unexpectingly LONG time when placed in a glass bowl. I was able to get one spinning for over 2 … 0
04:33 Rotational Inertia Demonstration – which is faster? Angular momentum = Omega x Inertia where Inertia = mR^2 Omega= Angular Velocity 0
