PART II. Given the distance-time data below of a car, compute for its speed. Make a distance-time graph and speed-time graph using the available data. Answer the questions that follow Distance in meter (m) Time in seconds (s) Speed (m/s) 0 m O s 0 3.5 15 3.5 m/s 7 2 s 10.5 3 5 10.5 4 5 14 5 s 21 6 s Distance-time Graph 1. Draw a line from the zero connecting all the dots. Describe the line which you have drawn 2. What can you say about the speed of the car during the 1-2 seconds? this indicate? 3. What can you say about the speed of the car between 3-4 seconds? What does 74 SCIENCE 7 / Third QuarterIn what time did the car speed up? Speed -time Graph 5. Draw a line connecting all the dots. Describe the line which you have drawn? What does it mean? 6. What information does a speed-time graph give you? 7. What can you say about the speed of the car? a between 1-2 seconds? b. between 3-4 seconds? C. between 5-6 seconds? 8. In what time interval is the car a. at rest b. not changing its speed c. speeding up or accelerating GENERALIZATION
