Velocity & Acceleration Graphing Grade #9 Name



Velocity & Acceleration Graphing Name_________________________Objective: To measure, chart, and graph distance, time and speed at three marks on a course. S8CS3aDirections:Get into groups of 5 or 6 students. Put each student doing a job. Record the jobs below.Job StudentFinish line timer30 m timer20 m timer10m timerRunner & subRunner & subReview how to use the timers and decide how each person will move along the track.Remember distance and displacement are the same since you will be traveling in one direction.Record each students travel style and time in the chart below: StudentStyle10m20m30m40mSpeed 10mSpeed 20mSpeed 30mSpeed 40mRunningWalkingWalking BackwardsSkipping2 foot hoppingSidewaysFigure out the speed for each student. Remember speed equals distance divided by time. S=d/tCreate a line graph for the 6 students in the following chart. Use a different color for each student. Be sure to label which student is represented by each color.18288004000500 (Distance is in meters)(Time is in seconds)StudentColorStudentColor142536Questions:Did any student go at a constant speed?___________________________What student was the fastest?________________________What student was the slowest?________________________Did any student show acceleration?________________________What problems did you encounter?______________________________What other observations can you make about this activity?Create a BAR GRAPH that depicts each students SPEED for their STYLE of motion.Use the same colors for each student that you used in the speed graph.***Remember you are only graphing SPEED and STYLE of motion. Acceleration:Calculate the acceleration for each style.StyleSpeed Initial (10m)Speed Final (40m)Time (40m)AccelerationSpeed at 20 m Speed at 30mRunningWalkingWalking BackwardsSkipping2 Foot HoppingSidewaysGraph: Use a Speed vs Time Graph to graph acceleration for your group. Do this on your own paper and attach it. Questions:1. Did any style accelerate? ______ Which? _______________________________________________________2. Did any style decelerate? ______ Which? ______________________________________________________3. What did the graph show you and what could you learn from it? ................
