5.2.2: Centripetal force

#5.2.2a

a constant net force perpendicular to the velocity of an object causes it to travel in a circular path

#5.2.2b

constant speed in a circle; $v = ωr$

#5.2.2c

centripetal acceleration; $a = \dfrac{v^2}{r}$ ; $a = ω^2r$

#5.2.2d

(i) centripetal force; $F = \dfrac{mv^2}{r}$ ; $F = mω^2r$

(ii) techniques and procedures used to investigate circular motion using a whirling bung.
