Angular Kinematics

Rotational kinematics are pretty much the same as linear kinematics(check that article for details) except for one main difference. The positive direction is by convention, counterclockwise and the negative direction is by convention, clockwise. Also, one great thing about the rotational kinematics equations is that they're analogous to their linear counterparts.

The first one is missing the change in angular displacement, the second is missing the time, the third is missing the final angular velocity, and the last is missing angular acceleration.

​

The good part about these equations is that there's no true concept of freefall motion. There's only one "axis" to consider rotational motion, so you don't need to double down to account for dimensions.

​

This is what makes rotational kinematics very intuitive because they're very similar to the ideas behind linear kinematics. If you understand linear kinematics, rotational kinematics are pretty much the same assuming you know the underlying principles behind the rotational motion.
