Learning objective
Master the angular quantities — angle of rotation, angular velocity, angular acceleration, period and frequency.
Derive the relations between linear and angular quantities ($v = \omega R$, $a_n = \omega^2 R$, $a_\tau = \varepsilon R$).
Learn to apply the equations of uniform and uniformly accelerated rotation.
Learn to solve problems on planetary motion and on transmissions (belt and gear drives).
Expected outcomes
Converts between period, frequency, angular and linear speeds.
Calculates the centripetal and total acceleration of a point moving in a circle.
Finds the number of revolutions and the angular acceleration in uniformly accelerated rotation.
Determines the ratio of rotation rates in belt and gear drives.
