Tangential and centripetal acceleration in circular motion

[QUOTE="BvU, post: 5698803, member: 499340"] Not really another thing. The little difference vector has a vanishing tangential component for ##\Delta t\downarrow 0## and also a vanishing component for the radial component. But the first one goes like cosine -1 and the second one like the sine of ##\Delta \theta##. So divided by ##dt## the first one gives zero and the second one ##-\omega^2 r ## in the limit ##dt \downarrow 0##. There are more accesible explanations -- is this adequate or is differentiation new for you ? [/QUOTE]
