Kinematics is the description of motion. The kinematics of rotational motion describes the relationships among rotation angle, angular velocity, angular acceleration, and time. To determine this equation, we recall a familiar kinematic equation for translational, or straight-line, motion:.

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.
Precalculus : Solve Angular Velocity Problems
The following questions are meant to guide our study of the material in this section. After studying this section, we should understand the concepts motivated by these questions and be able to write precise, coherent answers to these questions. In Section 1. So an arc of length 1 on the unit circle subtends an angle of 1 radian. There will be times when it will also be useful to know the length of arcs on other circles that subtend the same angle. So it follows that. It is important to remember that to calculate arc length , we must measure the central angle in radians.

1.4: Velocity and Angular Velocity
Find the angular velocity in radians per second. Find the angular speed of the car. Recall that. Note that radians is JUST a different way of writing degrees. The higher numbers in the answers above are all measures around the actual linear speed of the tire, not the angular speed. A car wheel of radius 20 inches rotates at 8 revolutions per second on the highway.

Angular Velocity and Linear Velocity Problems and Solutions
Determine the magnitude of the linear velocity of a point located :. Known :. Wanted : The linear velocity. Solution :. The blades in a blender rotate at a rate of rpm.
In this chapter rotational motion will be discussed. Angular displacement, angular velocity, and angular acceleration will be defined. The first two were discussed in Chapter 5.
