Here is a diagram showing the person moving in a straight line after leaving the merry go round. At the first position, the person has an angular velocity and moment of inertia of: Quick note: the "2" ...

Applications that require precise information on the linear or angular movement of an object rely on the accuracy of motion sensors within. Accelerometers and gyroscopes can be used to provide this ...

Introduction You might have seen figure skaters spinning around quickly and then tucking their arms to spin faster—or opening them to spin more slowly. This happens, thanks to a physics concept known ...
