2.2. Average Velocity http://www.ck12.org
- An object on a number line moved from x = 15 cm to x = 165 cm and then moved back to x = 25 cm, all in a
time of 100 seconds.
(a) What was the average velocity of the object?
(b) What was the average speed of the object?
- speed:Distance travelled per unit time.
- velocity:A vector measurement of the rate and direction of motion or, in other terms, the rate and direction
of the change in the position of an object.
