Rotation

Topic

When an object rotates about an axis, we refer to it as rotation. This is defined in terms of said axis, which corresponds to a vector, and the angle through which the object rotates.

If this angle changes over time, we can define an angular velocity as the rate of change of the angle with respect to time.

If the angular velocity changes over time, we can define an angular acceleration as the rate of change of the angular velocity with respect to time.

One of the interesting effects is the motion along an orbit, which to an external observer appears as a continuous fall towards the center. However, if an object does not remain in this orbit and begins to move away along a tangent line to the orbit at a constant speed, an observer within the rotating system would describe this motion as escaping from the center.
