2. 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?

CD

AB

BC

DE

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.

4. What is the meaning of the slope on a distance versus time graph?

Acceleration

Displacement

Velocity

Momentum

The slope on a distance versus time graph represents the speed or velocity of an object. In physics, speed is defined as the rate at which an object changes its position with respect to time. Mathematically, the slope of a distance-time graph is calculated as the ratio of the change in distance to the change in time.

5. 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?

AB

CD

BC

DE

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.

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.

6. The graph below represents the motion of an object. According to the graph, as time increases, the velocity of the object:

Increases

Decreases

Remains the same

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.

3

4

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.

9. Which of the following can be determined from a velocity-time graph?

The displacement of an object

The acceleration of an object

The initial velocity of an object

All of the above

A velocity-time graph provides information about an object's motion. The slope of the graph represents the acceleration, the area under the curve represents the displacement, and the y-intercept represents the initial velocity. Therefore, all of the above can be determined from a velocity-time graph.

10. 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

Three times as great

The same

One-third as great

Twice as great

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.
