Questions and Answers

1.

The graph below represents the motion of an object. According to the graph, as time increases, the velocity of the object:
- A.
  
  Increases
- B.
  
  Decreases
- C.
  
  Remains the same
Correct Answer
C. Remains the same

Explanation
According to the given graph, the velocity of the object remains the same as time increases. This can be observed by the horizontal line on the graph, indicating a constant velocity. Therefore, regardless of the passage of time, the object maintains a consistent velocity throughout its motion.

The displacement-time graph below represents the motion of a cart initially moving forward along a straight line. During which interval is the cart moving forward at constant speed?
- A.
  
  AB
- B.
  
  CD
- C.
  
  BC
- D.
  
  DE
Correct Answer
C. BC

Explanation
The cart is moving forward at constant speed during the interval BC. This is because the displacement-time graph shows a straight line segment, indicating that the cart is covering equal distances in equal time intervals. Since the slope of the line is constant, the speed of the cart remains constant during this interval.

Which graph best represents the motion of an object whose speed is increasing?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
Correct Answer
A. 1

Explanation
Graph 1 represents the motion of an object whose speed is increasing because the line on the graph is sloping upwards, indicating that the speed is increasing over time. Graphs 2, 3, and 4 either show a constant speed or a decreasing speed, so they do not represent an object with increasing speed.

The graph below shows the velocity of a race car moving along a straight line as a function of time. What is the magnitude of the displacement of the car from t = 2.0 seconds to t = 4.0 seconds?
- A.
  
  80. m
- B.
  
  20. m
- C.
  
  60. m
- D.
  
  40. m
Correct Answer
B. 20. m

Explanation
The magnitude of displacement can be found by calculating the area under the velocity-time graph between the given time interval. In this case, the area under the graph between t = 2.0 seconds and t = 4.0 seconds is a triangle with a base of 2 seconds and a height of 10 m/s. Therefore, the magnitude of displacement is (1/2) * 2 seconds * 10 m/s = 20 m.

Which graph best represents the motion of an object initially at rest and accelerating uniformly?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
Correct Answer
B. 2

Explanation
Graph 2 represents the motion of an object initially at rest and accelerating uniformly because it shows a steady increase in velocity over time. The slope of the graph is constant, indicating a constant acceleration. The object starts at rest and then accelerates uniformly in a straight line. The other graphs either show no acceleration, deceleration, or non-uniform acceleration.

The graph below shows the relationship between speed and time for two objects, A and B. Compared with the acceleration of object B, the acceleration of object A is
- A.
  
  Three times as great
- B.
  
  The same
- C.
  
  One-third as great
- D.
  
  Twice as great
Correct Answer
A. Three times as great

Explanation
The graph shows that the speed of object A increases at a faster rate compared to object B. This indicates that object A has a higher acceleration than object B. Since the question asks for a comparison, we can conclude that the acceleration of object A is three times as great as the acceleration of object B.

The graph below represents the relationship between distance and time for an object in motion. During which interval is the speed of the object changing?
- A.
  
  CD
- B.
  
  AB
- C.
  
  BC
- D.
  
  DE
Correct Answer
D. DE

Explanation
The speed of the object is changing during the interval DE. This can be inferred from the graph as the slope of the line DE is steeper compared to the other intervals. A steeper slope indicates a greater change in distance over time, which implies a change in speed.

What is the meaning of the slope on a distance versus time graph?
- A.
  
  Acceleration
- B.
  
  Displacement
- C.
  
  Speed
- D.
  
  Momentum
Correct Answer
C. Speed

Explanation
The slope on a distance versus time graph represents the rate at which an object is covering distance over time. In other words, it indicates the speed of the object. A steeper slope indicates a higher speed, while a flatter slope indicates a slower speed. Therefore, the correct answer is speed.
