Speed and Velocity Practice Flashcard

Front

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

Back

52 m/hr South

Front

How are speed and velocity different?

Back

Velocity has a direction while speed does not.

Front

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.

Back

The car changed velocity because the direction changed.

Back

8 km

Front

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

Back

0 km

Front

How are speed and velocity the same?

Back

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

Front

Are average velocity and instantaneous velocity always the same?

Back

False

Front

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

Back

True
