#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.
