Name: ____________________________ Block: _____________ Date: _________________ Speed of a Car – Activity Objective: In this activity students will determine the real life average speed of cars travelling down a straight road. Materials: Stopwatch Measuring Tape Data Table: Car Number Distance Travelled (meters) Time Travelled (Seconds) Analysis: Using the equation for average speed, determine the average speed for each car. Car Number Average Speed (m/s) Name: ____________________________ Block: _____________ Date: _________________ Conclusion Questions: Answer in COMPLETE SENTENCES! The speed limit in front of the school is 25 mph. Convert this value to meters per second. Were any of the cars speeding? How can you tell? Do you think our measurements were very accurate for the speed of the car? What could have caused us to calculate an incorrect speed for the car? A police office is sitting out front of the school and using the same distance the class did to determine if cars are speeding. How much time would the officer’s stopwatch read if the car is traveling 40 mph (15 mph over the speed limit)?
