Linear Motion Test Review 10/19/23

Which car is moving faster, A or B? How can you tell?

• A, because it looks faster

• B, because it has a steeper slope

• They both have the same velocity because both graphs are directed upward

Which car is moving faster, A or B?

• A, because it's slope is steeper

• B, because it starts at a higher location on the position axis

• B, because it ends farther from the reference point (0 meters)

• B, because it starts and ends farther from the reference point.

Which car reaches the greatest distance from the reference point in the time period shown on the graph?

• A, because it's slope is steeper

• B, because it starts farther from the reference point

• A, because it travels for farther during the time shown

• B, because it's final position is farther from zero than A's

Which of the following best describes the velocity of the car in the time period shown on the graph? (Choose 2 answers)

• Moving away from the reference point

• Moving toward the reference point

• Gaining speed

• Losing speed

Which car starts off ahead, where ahead means "farther from the reference point."

• A

• B

• They both start ahead because they both start at 0 seconds

How does the car's speed at 1 second compare to the car's speed at 3 seconds?

• It is faster at 3 seconds because the position value is greater

• It is faster at 3 seconds because the velocity is positive

• It is faster at 3 seconds because velocity is always in creasing in this graph

• It is faster at 1 second because the slope is steeper at 1 second

Which of the following statements is/are true about the motion of car A and car B based on the graph? Choose 2 answers!

• Car A is traveling faster than Car B because its slope is steeper

• Car A and Car B travel the same distance because their graphs end at the same position

• Car B travels farther than Car A because it travels for more time

• The two cars travel at the same velocity because they both move in the (+) direction and both end at the same position.

Which car is moving faster, A (solid line) or B (dotted line)?

• A, because it's slope is positive, so it has a positive velocity, which is faster.

• B, because it shows a car that is going downhill, so car B is getting faster.

• They are moving at the same speed, because the two graphs cross.

• They are both moving at the same speed, because their slopes are equally steep, just opposite directions.
