Completion requirements
In this section, students will gain an understanding of the concepts of angle of rotation and angular velocity in the context of circular and rotational motion. The angle of rotation is the angular equivalent of distance, and it represents the amount by which an object or a point on an object rotates about an axis. The angle of rotation is measured in radians, which are the angular equivalent of linear distance and correspond to the ratio of the length of an arc to the radius of the circle in which it is inscribed.
Angular velocity is the angular equivalent of linear velocity, and it describes how fast an object rotates with respect to time. The direction of the angular velocity is along the axis of rotation, with the right-hand rule serving as a useful tool to determine its direction. The tangential velocity is the instantaneous linear velocity of an object in rotational motion and can be calculated using the relationship between angular velocity and tangential velocity.
Through various examples, students will learn how to solve problems involving angle of rotation and angular velocity, and they will apply these concepts to real-world situations such as clock towers and spinning tires. The students will also complete a hands-on activity where they will create and measure uniform circular motion to contrast it with circular motions with different radii.
