Assertion: acceleration | /r/CapableOf | combine at low speeds
Facets:
value: to generate a coordinate acceleration
type: PURPOSE
Source sentences:
text: At low speeds these accelerations combine to generate a coordinate acceleration like a=d2x/dt2, while for unidirectional motion at any speed a o 's magnitude is that of proper acceleration α as in the section above where α = γ3a when a g is zero.
