Chapter 10, Problem 3A
Distinguish between linear speed and rotational speed.
Expert Solution & Answer
To determine
To explain: The difference between linear speed and rotational speed.
Explanation of Solution
Introduction:
Object moving in straight line has a linear motion and as linear velocity. Object rotating around a fixed axis have rotational speed.
Linear speed is the speed when objects moving in a straight line with velocity. It's SI unit is m/s. A car moving 10 m/s towards north.
Rotational speed is the speed with which object rotates around a axis. It is also known as angular speed. It’s SI unit is rad/s. A wheel rotating with rotating speed of 20 rad/sec.
Conclusion:
Linear sped is when object moves in straight line and rotating speed is along the axis around which object rotates.
