Which statement best describes a vector quantity?

• A car travelling due East

• A bus travelling West at 35 mph

• A bicyclist moving at 12 mph

• A child running in a circle

If a girl ran around all the bases on a baseball diamond, she would have traveled a distance of 360 feet. Her displacement, however, would be __________________.

• Greater than 360 feet

• Less than 360 feet

• Zero feet

• There are no bases on a baseball diamond

Two bicyclists travel from House 1 to House 2 as in seen in the figure above. Path A is straight and Path B is curved. Which path has greater displacement?

• Path A is greater

• Path B is greater

• Displacement is equal for both paths

• No one could live in a house that small

If a rooster were to lay an egg on the peak of a barn roof, which side would it roll down?

• Right Side

• Left Side

• Depends on if the wind is blowing

• It wouldn't roll down either side.

If a jogger runs in a large circle at a constant speed, will her velocity also be constant?

• No

• Yes

• Only if the wind isn't blowing

• Yes, if she's on level ground

If a rabbit runs in a zigzag path from a carrot patch back to his burrow, which will be greater - the distance traveled or the displacement?

• The distance traveled

• The displacement

• Both will be the same

• Rabbits always run in straight lines
