Speed and Velocity Practice Quiz

1. Which of the following is a complete velocity measurement?

• 25 m/s

• 1500 km/hr

• 52 m/hr South

• all of these are velocity measurements

2. How are speed and velocity different?

• Speed involves how fast something moves while velocity does not.

• Velocity has a direction while speed does not.

• There is no difference between speed and velocity.

• Velocity has a magnitude while speed does not.

3. A car maintains a constant speed of 15 km/hr while going around a curve to the left. Which of the following is true?

• The car changed velocity because it decreased speed.

• The car did not change velocity.

• The car changed velocity because it increased its speed.

• The car changed velocity because the direction changed.

4. A runner ran in a straight line with a constant speed of 5 km/hr. Which of the following is true? (Choose all correct options.)

• The runner did not change speed.

• The runner did not change velocity.

• The runner did not change direction

• The runner changed speed.

• The runner changed velocity.

7. The change in an object's position from the final position to initial position is described as _?_.

• displacement

• distance

• motion

• reference point

9. Pat walked from home to school, then from the school to the park. What was Pat's total distance?

• 2 km

• 5 km

• 8 km

• 10 km

11. Bill runs 10 kilometers to Andy's house, turns around, and runs 10 kilometers back home. What is Bill's displacement?

• 0 km

• 20 km

• 10 km

• 100 km

12. How are speed and velocity the same?

• Speed calculations involve distance and velocity calculations involve displacement.

• Velocity has a direction while speed does not.

• Speed and velocity measurements are exactly the same.

• Speed and velocity are both represented by the variable 'v' in formulas.

13. Average velocity and Instantaneous velocity are always the same.

• True

• False

14. Average velocity and Instantaneous velocity are the same if the object has constant motion.

• True

• False
