Centripetal acceleration via vector rejection¶
Centripetal acceleration is the acceleration of a body in a rotating coordinate system which is directed towards the axis of rotation.
Also see Centripetal acceleration via cross product.
Notation:
\(\left( \vec a, \vec b \right)\) (
dot(a, b)
) is the dot product between vectors \(\vec a\) and \(\vec b\).
