In some cases the repeats of a "perpetuum mobile" piece are at a different pitch, a modulation or a chord progression occurs during the repeatable part. Some of the riddle canons of Bach's Das Musikalische Opfer are examples of this particular kind of perpetuum mobile/canon perpetuus. [citation needed]
Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an external energy source. This kind of machine is impossible, since its existence would violate the first and/or second laws of thermodynamics. [2] [3] [4] [5]
The same motion described in a different coordinate system will be represented by different numbers, and vector algebra can be used to translate between these alternatives. [9]: 4 The study of mechanics is complicated by the fact that household words like energy are used with a technical meaning.

Motion can be mathematically described in terms of displacement, distance, velocity, speed, acceleration, and momentum, and is observed by attaching a frame of reference to an observer and measuring the change in an object's position relative to that frame. An object's motion cannot change unless it is acted upon by a force. muon
