Rotational Kinematics (Circular Motion)

Basic Rotational Kinematics Problems (Angular Motion)

This video covers examples about how to use the rotational kinematics formulas to solve for angular acceleration, angular velocity, and angular displacement (Θ). If the formulas in the video don't look familiar, you should definitely watch the first video on this page first.

Gear Ratio Rotational Kinematics Problems

If you've ever ridden a bike, you've experienced a gear ratio (technically cogs): the larger front gear turns slower than the gear on the back wheel. This video has examples about bikes and wind mills (which also have gears in them), analyzing the angular velocity and acceleration of one gear compared to the other.
