Module 2- Motion Test

1. At 8:00 AM you leave home and walk 0.5 km to a friend's house. At 11:30 AM you return home, then travel by car to the mall, which is 10 km away, and arrive at 11:45 AM. What is the total distance traveled?

• 2.8 km/h
• 10 km
• 10.5 km
• 11 km

3. Average speed is found by

• multiplying total distance traveled by the total time
• multiplying the displacement by the total time spent
• dividing the displacement by the total time spent
• dividing total distance traveled by the total time

4. __________ is the speed of an object at any instant of time.

• acceleration
• average speed
• instantaneous speed
• velocity

5. The direction and speed of an object is described by its ______________?

• average displacement
• average speed
• displacement
• velocity

6. Bill ran a distance of 10.5 km in 32 min. What is Bill's average running speed?

• 0.33 km/min
• 3.0 km/min
• 3.3 km/min
• 330 km/min

7. If an object has a constant velocity, then it __________.

• has a negative acceleration
• has an acceleration of zero
• has a positive acceleration
• is not moving

8. A change in velocity means a change in ___________.

• direction only
• speed only
• speed, direction, or both
• always both speed and direction

9. Motion is described with respect to a

• graph
• slope
• frame of reference
• displacement

10. Acceleration is equal to

• distance divided by time
• change in velocity divided by time
