QUESTION 4 Which of the following has the greatest displacement? Assume the motion is along the perimeter of the shapes and that they start and end in the same place. MD Each side is 1m long. 717 Each side 1m long 0 c. The diameter is 1m long O d.All have the same displacement Each side is 1m long. QUESTION 5 A car travels along a winding road, speeding up and slowing down as it goes. The car ends up 30 km directly north of its starting point after 40 minutes of travel. Three students make the following statements of the situation: Adian: \"I think if we calculate the average velocity and average speed for the car. the average velocity would have a larger value. The velocity includes direction which will increase the value of the velocity. The speed will be less than the velocity. Bradley: \"I think the average speed will be larger than the average velocity. The road is not straight so the distance will be larger than the displacement. Cici: "I don't see any difference in the value of the average velocity and average speed. They are just different names for the same measurements. Which of the students do you agree with? O a. None, they are all incorrect. O b. Cici O c. Adian Q d. Bradley QUESTION 1 What are the two important measurements for motion? 0 a. time and acceleration O b. acceleration and velocity 0 :2. length and time 0 d. velocity and length QUESTION 2 True or False - The measurement \"30 mil'hr West" is likely a scalar quantity. 0 a. True, scalars have a directional component 0 b. True, scalars can only be speed measurements 0 c. False, this is a vector because its has magnitude only 0 d. False, this is a vector because it has a directional component QUESTION 3 Which of the following has the greatest distance? Assume the motion is along the perimeter of the shapes and that they start and end in the same place. 0a. i Each side 1m long mm Each side is 1m long. 0 c. All have the same distance Each side is 1m long. Q The diameter is 1m long QUESTION 6 Which value has the greatest mgm of displacement? O a.45m O b.-13 m 0 c. 0 m 0 d.- 500m QUESTION 7 A friend says that if a car is moving toward the east. it cannot at the same time accelerate toward the west. O a. The friend is right. The acceleration and velocity of the car always have the same direction. the car always accelerates. O b. The friend is wrong. The acceleration of the car is always in direction opposite to its velocity, the car always decelerates. O c. The friend is wrong. When acceleration of the car is in direction opposite to its velocity, the car is decelerating. QUESTION 8 Suppose you are in a car that is going around a curve. The speedometer reads a constant 30 miles per hour. Which of the following is NOT true? 0 a. Your velocity is constant. b. Y0ur acceleration is constantly changing. c. Your speed is constant. d.Your direction is constantly changing. 2. You and the car are accelerating. OOOO QUESTION 9 Which of the following would NOT be considered an acceleration O a. a runner reunds the bend of the track 0 b. a runner changes speed from a slow pace to a faster pace 0 c. a runner maintaining their speed in a straight line 0 d.starting from rest, a runner begins a race QUESTION 10 How many "gs" does a person experience if they have an acceleration of 50 m/s?? O a. 490.5 gs O b. 40.19 gs O c. 1g O d. 5.09 gs QUESTION 11 Which of the following exhibits free fall motion? O a. snow falling O b. train moving on a flat track O c. a snowball in flight after being thrown O d. pendulum on a string QUESTION 12 A book and a flat piece of paper were held at the same height and then dropped at the same time. What was the outcome and why? O a. They both hit at the same time. O b. The book hit first because it had a greater effect from air resistance O c. The paper hit first because it had more air resistance O d. The book hit first because the paper had more effect from air resistance QUESTION 13 When a crumbled piece of paper and a book were held at the same height and dropped at the same time, what was the outcome and why? O a. The book hit first because it had a larger area than the crumbled piece of paper O b. The crumble of paper hit first because it was smaller than the book, thus had less mass and could move faster. O c. The crumble of paper and the book hit at the same time, because all objects have the same acceleration when air resistance is negligible. O d. The book hit first because heavier objects have more accelerationQUESTION 14 The value "g" is physics represents O a. the constant force of falling objects 0 b.the constant displacement of falling objects 0 c. the constant speed of falling objects 0 d. the constant acceleration of falling objects QUESTION 15 Professor Granucci throws a baseball straight up. What are the vectors as its moving upward? O a. the velocity is upward. the acceleration is upward O b.the velocity is downward, the acceleration is downward O c. the velocity is downward. the acceleration is upward O d.the velocity is upward. the acceleration is downward QUESTION 16 d (m) Select segment(s} that represents forward motion? Select all that apply. [7 a.AB [1 b. None of the segments represent forward motion [7 c. C-D [7 d.B-C [1 e. D-E QUESTION 17 d (m) Select segment(s) that represents an acceleration? Select all that apply. [7 a. (3-0 [7 b.AB [7 c. D-E [7 d.B-C [7 e. None of the segments represent acceleration QUESTION 18 d (m) 107 B 8- C D 1 (S) 1.0 2.0 Which segment has the fastest average velocity? O a. B-C O b. A-B O c. None of the segments represent acceleration O d. D-E O e. C-DQUESTION 19 d (m) 107 8- B C N A D 1.0 2.0 at bol E What is the average velocity of segment C-D? O a. -0.5 m/s O b. 0 m/s O c. 2 m/s O d. 20 m/s O e. -20 m/sQUESTION 20 d (in) In the segment of acceleration. what is the object doing? [1 a. speeding up backward [1 b. slowing down forward [1 c. there was no acceleration segment [1 d.slowing down backward [1 e. speeding up forward
