Chapter 1 Lesson 2 Speed and Velocity

The velocity of an object is the same as its speed except that velocity specifies the direction of motion.

If you set "cruise control" on your car to 60 mph, your car's instantaneous speed is equal to your constant speed.

This graph represents something moving at a constant speed.

What colored line represents a moving object with the fastest velocity? Options: red, orange, blue, green

What colored line represents a moving object with the slowest velocity? Options: red, orange, blue, green

What colored line represents an object that is stopped and has a velocity of 0 m/s? Options: red, orange, blue, green

How can you calculate average speed from a distance-time graph?

Which choice is a unit of speed? Options: h/mi, km/h, m^2/s, N \cdot m

At what number of seconds did the moving object change direction from a positive reference direction to a negative reference direction?

total distance / total time
