Circular Motion
... Remember that velocity is a vector. Vectors have a magnitude and direction. For velocity this would be speed and direction. So… aT changes the speed and ac changes the direction. Here are 2 examples that have both tangential ( aT ) and centripetal ( ac ) acceleration. (Luckily for us, the AP Physics ...
