Exam Name___________________________________MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

1. 1)  Consider a deer that runs from point A to point B. The distance the deer runs can be greater than 1) the magnitude of its displacement, but the magnitude of the displacement can never be greaterthan the distance it runs.A) True B) False
2. 2)  Which of the following quantities has units of a displacement? (There could be more than one 2) correct choice.)A) 186,000 miB) 32 ft/s2 vertically downwardC) 9.8 m/s2 D) -120 m/sE) 40 km southwest
3. 3)  Suppose that an object travels from one point in space to another. Make a comparison between the 3) magnitude of the displacement and the distance traveled by this object.A) The displacement can be either greater than, smaller than, or equal to the distance traveled. B) The displacement is always equal to the distance traveled.C) The displacement is either less than or equal to the distance traveled.D) The displacement is either greater than or equal to the distance traveled.
4. 4)  Consider a car that travels between points A and B. The car’s average speed can be greater than 4) the magnitude of its average velocity, but the magnitude of its average velocity can never begreater than its average speed.A) True B) False
5. 5)  Which of the following quantities has units of a velocity? (There could be more than one correct 5) choice.)A) 186,000 miB) 9.8 m/s downwardC) 9.8 m/s2 downward D) 40 km southwestE) -120 m/s
6. 6)  When is the average velocity of an object equal to the instantaneous velocity? 6) A) neverB) when the velocity is constantC) only when the velocity is increasing at a constant rate D) only when the velocity is decreasing at a constant rateE) always

7. 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 7) km drive will beA) less than 70 km/h.B) greater than 70 km/h.C) equal to 70 km/h. D) exactly 38 km/h.E) It cannot be determined from the information given because we must also know directions traveled.
8. 8)  If the velocity of an object is zero at some point, then its acceleration must also be zero at that 8) point.

A) True B) False9) Which of the following situations is impossible?A) An object has constant non-zero acceleration and changing velocity.B) An object has zero velocity but non-zero acceleration.C) An object has constant non-zero velocity and changing acceleration. D) An object has velocity directed east and acceleration directed west.E) An object has velocity directed east and acceleration directed east.

9)

10. 10)  If the acceleration of an object is zero, then that object cannot be moving. 10) A) True B) False
11. 11)  If the velocity of an object is zero, then that object cannot be accelerating. 11) A) True B) False
12. 12)  Suppose that a car traveling to the west begins to slow down as it approaches a traffic light. Which 12) of the following statements about its acceleration is correct?A) Since the car is slowing down, its acceleration must be negative. B) The acceleration is toward the east.C) The acceleration is toward the west. D) The acceleration is zero.
13. 13)  An auto manufacturer advertises that their car can go “from zero to sixty in eight seconds.” This is 13) a description of what characteristic of the car’s motion?A) instantaneous speed B) average accelerationC) average speed D) displacementE) instantaneous acceleration
14. 14)  An object moving in the x direction experiences an acceleration of 2.0 m/s2. This means the 14) objectA) is increasing its velocity by 2.0 m/s every second. B) travels 2.0 m in every second.C) is decreasing its velocity by 2.0 m/s every second. D) is traveling at 2.0 m/s.
