This worksheet focuses on interpreting distance-time graphs and matching different parts of a graph with corresponding motion descriptions. Let's analyze and solve the questions step by step.

Analysis:

1. Distance-Time Graphs:

   • Graph 1: Straight, upward-sloping line indicates constant speed.
   • Graph 2: Horizontal line shows no movement (stationary).
   • Graph 3: Curved line indicates changing speed (either speeding up or slowing down).

2. Matching Descriptions for Graphs:

   • Graph 1 matches "the car is traveling at constant speed."
   • Graph 2 matches "the car is stopped."
   • Graph 3 matches "the speed of the car is decreasing."

3. Second Section:

   • Stationary (horizontal line): Corresponds to part B.
   • Increasing speed (steeper slope): Likely part E.
   • Slow & constant speed: Matches part C.
   • Fast & constant speed: Matches part D.
   • Returning to start: Matches part A.

4. Summary Observations:

   • A steeper graph implies faster motion.
   • Horizontal line represents no movement.
   • A curved line shows acceleration or deceleration.

Would you like further clarification on these solutions or detailed explanations for the concepts?

Follow-Up Questions:

1. What does the slope of a distance-time graph represent in physical terms?
2. How can you tell from a graph when an object changes direction?
3. What is the significance of a curved line on a distance-time graph?
4. How would the graph change if the speed continuously increased?
5. How can you calculate speed from a distance-time graph?

Tip:

The slope of the line on a distance-time graph gives the speed of the object. A steeper slope means a higher speed.
