Answer:
1. An object travels 7 meters to the left, then 6 meters down, then another 7 meters to the right. Which of the following statements is true about the object's motion? a. The displacement of the object is equal to 6 meters down. b. The displacement of the object is equal to 7 meters to the right. The total distance travelled by the object is equal to 14 meters. d. The total distance travelled by the object is equal to 20 meters. C. 2. A body is said to be in motion when it undergoes a continuous change in its position with respect to a fixed reference point called the origin. Which of the following statements describe that a body is in motion? 1 - When its position changes with respect to a point of reference. 11 -- When its distance changes with respect to a point of reference. III - When its direction changes with respect to a point. a. b C. d. ه ي م ه I and ll only I and Ill only II and III only I, II, and III 3. An object travels along a straight path with a uniformly increasing velocity. How shall we describe the motion of the object? a. The object is travelling with a displacement equivalent to half its distance. b. The speed of the object is constant with respect to its point of origin. C. The object is travelling with a constant acceleration. d. The velocity of the object is proportional to its displacement. 4. An athlete covered a distance of 360 meters after running for two (2) minutes. What is the average speed of the athlete? a. 3.0 m/s b. 3.5 m/s C. 4.0 m/s d. 4.5 m/s 5. The distance vs time graph of an object shows a horizontal line. How shall we describe the motion of the object? a. The object is moving with a constant speed. b. The object is at rest. c. The object is speeding up. d. The object is slowing down. 6. The speed of an object represents how fast or how slow it moves. What term is used in Physics when the speed of an object has a particular direction? a. acceleration b. displacement c. velocity d. distance _7. If an object is neither speeding up nor slowing down, we say that the speed of the object is constant. Which of the following statements describes an object with a constant speed? The object is not accelerating. The speed of the object is equal to zero. The distance travelled by the object remains constant. . The displacement of the object is zero. doo a. b C. 1
