A centripetal force (frae Laitin centrum, "centre" an petere, "tae seek"[1]) is a force that maks a bouk follae a curved path. Its direction is always orthogonal tae the motion o the bouk an towards the fixed pynt o the instantaneous centre o curvatur o the path. Isaac Newton describit it as "a force bi which bouks are drawn or impelled, or in ony way tend, taewart a pynt as tae a centre".[2] In Newtonian mechanics, gravity provides the centripetal force responsible for astronomical orbits.
