Math Problem Statement

Match the descriptions with the appropriate parts of the distance-time graphs and analyze the motion described in the worksheet.

Solution

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.

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.
