The Physics 500
I. Problem:
Part 1: Determine a method to find your average velocity of a person as he/she walks, hops, rolls, or moves in a straight line in one direction.
Part 2: Use information from Part 1 to determine a marked distance without a measuring tape or ruler.
Part 3: Gather data to create a graph to determine your speed using the graph and then compare to the speed you found in Part 1.

Part 2 Methods:
1. Use your data from Part 1 to determine a marked distance on the ground.You only get one trial so try to move just like you did for Part 1 for best results.
2. Record any information below you need to determine distance by YOU.
3. Make a 5 step calculation for distance
4. Check the actual distance from your teacher and record.
5. Calculate your % error.
Data: _____________ ______________ Path used: _________

Part 3 Methods:
1. Find another group so you have at least 8 people.
2. Choose TWO people to be the ÒmoversÓ
3. Mark off 1 meter intervals and station the other people (6 or more) at the interval marks with a stopwatch.
4. Have the ÒmoversÓ race by the people at the marks and record the time and distances in the table below.

IV. Questions
1.What did you need to measure to determine velocity?
2. In words, describe how you can use a known velocity to find an unknown distance.
3. What part of a position time graph represents the velocity of the object?
4. How did the slopes of the lines for the graphs of the 2 racers compare? Which slope did the slower racer have (shallower or steeper)?
