Graphs & Problem Solving

📈 A) Position–Time Graph (Answer clearly)

For each case, write what is happening to the object:

1. A straight line going up → __________________

2. A horizontal line → __________________

3. A steeper straight line → __________________

📉 B) Velocity–Time Graph (Interpret)

For each case, describe the motion:

1. Horizontal line → __________________

2. Line going upward → __________________

3. Line going downward → __________________

🔍 C) Analyze a Graph (Explain in words)

Answer in one sentence each:

1. What does the slope represent in a position–time graph?

2. When is velocity constant?

3. When is acceleration present?

🧠 D) Hypothesis & Prediction

1. A car travels 90 m in 3 s.
   → Velocity = ______

📐 E) Solve

1. A runner moves 150 m in 15 s.
   → Velocity = ______

2. A car moves at 20 m/s for 5 s.
   → Distance = _____

✏️ F) Full Reasoning

A car travels 200 m in 8 s.

→ Velocity = ______
→ Explain the result in a real-world context: __________
