MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) Consider a deer that runs from point A to point B. The distance the deer runs can be greater than the magnitude of its displacement, but the magnitude of the displacement can never be greater than the distance it runs. 1) A) True B) False 2) Which of the following quantities has units of a displacement? (There could be more than one correct choice.) 2) A) 32 ft/s2 vertically downward B) 9.8 m/s2 C) 40 km southwest D) 186,000 mi E) -120 m/s 3) Suppose that an object travels from one point in space to another. Make a comparison between the magnitude of the displacement and the distance traveled by this object. 3) A) The displacement is either greater than or equal to the distance traveled. B) The displacement is always equal to the distance traveled. C) The displacement can be either greater than, smaller than, or equal to the distance traveled. D) The displacement is either less than or equal to the distance traveled. 4) Consider a car that travels between points A and B. The car's average speed can be greater than the magnitude of its average velocity, but the magnitude of its average velocity can never be greater than its average speed. 4) A) True B) False 5) Which of the following quantities has units of a velocity? (There could be more than one correct choice.) 5) A) 40 km southwest B) 9.8 m/s downward C) 9.8 m/s2 downward D) 186,000 mi E) -120 m/s 6) When is the average velocity of an object equal to the instantaneous velocity? 6) A) when the velocity is constant B) only when the velocity is increasing at a constant rate C) never D) only when the velocity is decreasing at a constant rate E) always 7) You drive 6.0 km at 50 km/h and then another 6.0 km at 90 km/h. Your average speed over the 12 km drive will be ..................................................continued.....................................................
