A basketball player runs the full length of the court, turns around, and runs back. He then runs back down again to the opposite side.

Which of the following statements are true?

• the player's displacement is greater than their distance

• the player's distance is greater than their displacement

• the player's distance and displacement are equal

• cannot determine which is greater w/o more information

Which of the following statements regarding distance and displacement is true?

• Distance and displacement can never be the same magnitude

• Neither distance nor displacement have direction associated with them

• displacement can be equal to distance if object never changes direction

• displacement is always greater than distance

The SLOPE of the displacement vs time graph is equal to the

• distance

• velocity

• acceleration

• position

What does it mean to be a scalar quantity?

• scalar quantities have magnitude but no direction

• scalar quantities have magnitude and direction

• scalar qualities have scales, like dragons, they're pretty cool

• scalar quantities only exist in the 4th dimension

What is the position of the object at t = 70 seconds?

• 0 m

• 60 m

• 70 m

• -30
