An angular momentum is a characteristic of an angular motion such as rotation. This value is the mathematical product of the angular velocity and the momentum of inertia. The momentum of inertia plays the same role in the angular motion as the mass does in the linear motion. The momentum of inertia

Creating smoke or fog on demand uses dry ice. Dry ice is the solid state of carbon dioxide. The smoke created by dry ice is the carbon dioxide sublimating and returning to a gaseous state. Sublimation is the process of a solid becoming a gas without ever entering a liquid state. Dry ice smokes for a
