D) Distance traveled is always more than displacement. (e) Distance traveled is greater than or equal to displacement. 2 Velocity and Speed Describing Motion Average Velocity and Average Speed You developed an intuitive feel for motion long before taking physics. You sense the difference between driving at 30 miles per hour and going 60. Those are measures of speed, an important quantity in describing motion. You ve probably also used the term velocity, which is related to speed but not exactly equivalent.

Car slows down: Negative slope : negative acceleration (ax 6 0). Constant speed: Zero slope : zero acceleration (ax = 0). Time, t (a) Car traveling in +x -direction Velocity, vx Acceleration can be positive, negative, or zero. 15a. The graph shows that positive acceleration corresponds to increasing velocity, zero acceleration to constant velocity, and negative acceleration to decreasing velocity. Careful! That s velocity, not speed. 15b. What about your acceleration? At the start of this trip, your speed the magnitude of your velocity is increasing, but the velocity is getting more negative, and thus the acceleration is negative, too.

But what happens throughout each interval? 6 s? That would require more data namely, positions at smaller time intervals. 01 s. 00 s. 01 s. 00 s as shown in the table. 8 m>s. If you had data for even smaller intervals and more precise positions, you would see that the average velocity does approach one value, in the limit as the time interval ¢t approaches zero. That value is the instantaneous velocity. 4 as the definition of the derivative, with the shorthand notation vx = dx>dt. We won t use calculus in this book, so you won t be asked to compute exact values of instantaneous velocity.
