... In the figure, a disk, a hoop and a solid sphere are made to spin about fixed central axis (like a top) by means of strings wrapped around them, with the string producing the same constant tangential force F on all three objects. The three objects have the same mass and radius, and they are initial ...

Moment of Inertia for Bicycle Wheel
... For the activity that we have planned today, you and a partner will work together to find the moment of inertia for a wheel that is being accelerated by a falling weight. Some things that you will need to keep in mind while completing this task is that you will have to look at the motion of the fall ...

... (3) If body 1 exerts a force F~ on body 2, then there must be a force −F~ acting on body 2 due to body 1. Therefore, in an isolated system, all forces must sum to zero. There’s not too much to say about this chapter... it all becomes clear when we apply these principles to specific problems as we ha ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
