What is Your Average Walking Velocity?
How will you figure this out?
Rate of travel = Velocity,for our purposes.
If Rate Time Distance, then what is Rate ?
How to Collect Data• Form a group of three people.• The timer will say “go” and call out the time
every 2 seconds for 16 seconds. • The walker will walk steadily for 16 seconds• The marker will walk alongside the walker and
drop a a large paper clip on the floor beside the walker every 2 seconds to designate the position of the walker.
Distance Traveled is a Function of Time
• Measure the distance from each marker to the starting point, noting the corresponding time.
• What are the two variables? Which is the independent variable; which the dependent?
• Make a table and a graph. x= y=
Ready, Set, Go…..
Now pick up the following supplies:• Student Worksheet• 8 markers such as large paper clips• tape measure• time piece
