Facets:
value: by the trajectory of the particle
type: OTHER
value: by arc length
type: OTHER
Source sentences:
text: The quantity s is used to give the curve traced out by the trajectory of the particle a natural parametrization by arc length, since many different particle paths may trace out the same geometrical curve by traversing it at different rates.
