Defining Velocity

Topic: VelocityDate: 9/26/2012

DefinitionsAverage velocity is the velocity over the whole time period.Instantaneous velocity is the velocity over a small time period.

1. What is the average velocity of the car across this trip?

A. 25km/h B. 50km/h C. 75km/h D. 100km/h

2. What is the instantaneous velocity of the car between 4 and 7 hours? A. 25km/h B. 50km/h C. 75km/h D. 100km/h

3. During which time interval does the car have the fastest speed? A. 1-2 hours B. 2-3 hours C. 4-7 hours D. 9-10 hours

4. During which time interval does the car have zero velocity? A. 1-2 hours B. 2-3 hours C. 4-7 hours D. 9-10 hours
