The area under a velocity-time graph gives the displacement. The velocity-time and acceleration-time graphs for common motions are shown below.

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Another basic question people have been asking: why do we feel acceleration, but not velocity? One person recently effectively asked this in the "Physics Is Fun" Facebook group.
