Appendix B Linear and Angular Velocity
Linear Velocity When an object travels a distance s along any path in time t, its linear velocity v or linear speed is defined to be
EXAMPLE 1 Linear Velocity
The linear velocity of a runner who finishes a 10 km race in 1.25 h is given by
You might recognize (1) in the more familiar form 5 = vt, that is, distance = rate X time.
Angular Velocity Now consider a point P on a circle of radius r shown in figure ...
