Problem
A student graphs the angular position θ (in radians) of a rotating wheel as a function of time t (in seconds). The graph is a straight line with positive slope. Which physical quantity does the slope of the θ–t graph most directly represent?
(a) the wheel’s angular acceleration
(b) the wheel’s angular velocity
(c) the tangential speed of a point on the rim
(d) the wheel’s rotational frequency (revolutions per second)
