The ratio of their angular speeds can be determined as follows: Definition of Angular Speed Angular speed is defined as the rate of change of angular displacement with respect to time. This means that the minute hand rotates 12 times faster than the hour hand.

The learning objectives in this section will help your students master the following standards:. What exactly do we mean by circular motion or rotation? Rotational motion is the circular motion of an object about an axis of rotation. We will discuss specifically circular motion and spin. Circular motion is when an object moves in a circular path. Examples of circular motion include a race car speeding around a circular curve, a toy attached to a string swinging in a circle around your head, or the circular loop-the-loop on a roller coaster. Spin is rotation about an axis that goes through the center of mass of the object, such as Earth rotating on its axis, a wheel turning on its axle, the spin of a tornado on its path of destruction, or a figure skater spinning during a performance at the Olympics. Sometimes, objects will be spinning while in circular motion, like the Earth spinning on its axis while revolving around the Sun, but we will focus on these two motions separately. When solving problems involving rotational motion, we use variables that are similar to linear variables distance, velocity, acceleration, and force but take into account the curvature or rotation of the motion. Here, we define the angle of rotation , which is the angular equivalence of distance; and angular velocity , which is the angular equivalence of linear velocity.
