Distance – Time Graph A. Choose the Correct Answer: 1. What does the slope of a distance-time graph represent? A) Distance covered B) Speed of the object C) Time taken D) Acceleration 2. If a distance-time graph is a straight line parallel to the time axis, what does it indicate? A) The object is moving with constant speed B) The object is at rest C) The object is accelerating D) The object is moving backward 3. Which of the following distance-time graphs represents uniform motion? A) A curved line B) A zigzag line C) A straight-line sloping upwards D) A straight-line sloping downwards B. Fill in the Blanks: 1. A distance-time graph is used to represent the __________ of an object over time. 2. The steeper the slope of a distance-time graph, the __________ the speed of the object. 3. A horizontal line on a distance-time graph indicates that the object is __________. C. Case Study: A student named Rohan conducted an experiment to observe the motion of a toy car on a smooth surface. He recorded the distance covered by the car at regular time intervals and plotted a distance-time graph. Observations: • The graph was a straight line sloping upwards. • The car covered equal distances in equal time intervals. • The speed remained constant throughout the experiment. Case Study Questions: 1. What type of motion did Rohan’s toy car exhibit? 2. What does the straight-line graph indicate about the speed of the car? 3. If the graph had been a curved line, what would it signify? 4. How can we determine the speed of the toy car using the distance-time graph? D. Short Answer Questions: 1. What is a distance-time graph? 2. How can we determine if an object is in uniform or non-uniform motion using a distance-time graph? 3. What does a steeper slope in a distance-time graph indicate? E. Long Answer Questions: 1. Explain the different types of distance-time graphs and their significance. 2. How can a distance-time graph be used to calculate speed? Explain with an example. 3. Describe a real-life situation where a distance-time graph can help in understanding motion.
