A) True B) False Answ er: B Var: 1 2) If the graph of the position as a function of time for an obje ct is a horizontal line, that obje ct cannot be accelerating. A) True B) False Answ er: A Var: 1 3) If an object is accelerating tow ard a point, then it must be g etting clos er and closer to that point. A) True B) False Answer: B Var: 1 4) When can we be certain that the average velocity of an obje ct is always equal to its instant aneous v elocity? A) always B) never C) only wh en the v elocity is constant D) only wh en the acceleration is constant E) only wh en the acceleration is changing at a constant rate Answer: C Var: 1 5) Suppose that an obje ct is moving w ith constant nonzero acceleration. Which of the followi ng is an accurate statement concerning its m otion? A) In equal times its spe ed changes by equal amounts. B) In equal times its v elocity ch anges by equal amounts.
