<p>MEASURING SPEED AND ACCELERATION</p><p>1. Measure out 15 meters on the ground. Mark both ends with tape. Stand on one piece, and walk to the other piece of tape. A partner will time you. Do this walk three times. Write the times below in seconds: (You can measure a person with a watch’s second hand, or you can count off the seconds by saying, “one, one thousand, two, one thousand, three, one thousand, etc.)</p><p>1. ______2. ______3. ______</p><p>Now have your partner do the walk three times and you time your partner. Write the times below:</p><p>1. ______2. ______3. ______</p><p>2. Find the average speed of yourself and then your partner. Use the formula for average speed: total distance / total time = average speed</p><p>Write your answer for you and your partner below: (Don’t forget the units: m/sec.)</p><p>Your average speed: Your partner’s average speed:</p><p>Describe your velocity. Velocity is speed and direction. Write your average speed and include the direction you were going (north, south, towards the office, etc.)</p><p>3. Were you accelerating during this exercise (speeding up, slowing down, or changing direction? (Describe how you were accelerating)</p><p>4. Find your average acceleration by plugging in your initial speed (which was zero), your final speed (your average speed from above), and your average time (take your total time and divide by three) into the formula below.</p><p> final speed – initial speed /average time = average acceleration</p><p> initial speed = 0m/s final speed (your average speed from above) = ______average time (add your three times together and divide by three) = ______</p><p>Now find your average acceleration using the formula above. Show your work below.</p><p>5. Write your acceleration here: ______</p>
