Find the angular velocity in radians per second. Find the angular speed of the car. Recall that.
Chapter 8. Rotational Kinematics:. Although these quantities were discussed in Chapter 5, we will review them here again.
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:. It is also precisely analogous in form to its translational counterpart. Starting with the four kinematic equations we developed in One-Dimensional Kinematics , we can derive the following four rotational kinematic equations presented together with their translational counterparts :. A deep-sea fisherman hooks a big fish that swims away from the boat pulling the fishing line from his fishing reel. The whole system is initially at rest and the fishing line unwinds from the reel at a radius of 4.
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.
