Let's analyze each question based on the described graphs:
Question 3
Description: The graph represents a straight line with T (time) on the x-axis and D (distance) on the y-axis.
- Interpretation: A straight line on a distance vs. time graph indicates that distance is changing at a constant rate, meaning the object is moving at a constant speed.
Correct Answer: constant speed
Question 4
Description: The graph starts from 0 and goes up, with D (distance) on the y-axis and T (time) on the x-axis.
- Interpretation: If the graph starts from 0 and goes upwards, this indicates an increase in distance over time, suggesting that the object is speeding up from rest, which indicates acceleration.
Correct Answer: acceleration
Question 5
Description: The graph is a straight line with V (velocity) on the y-axis and T (time) on the x-axis.
- Interpretation: A straight line on a velocity vs. time graph indicates that velocity is constant over time. The object is not changing its speed or direction.
Correct Answer: constant velocity
In summary, the answers are:
- Question 3: constant speed
- Question 4: acceleration
- Question 5: constant velocity
