Introduction to Motion
Investigation 1:
Distance(Position)-Time Graphs of Your Motion
To find out How you can measure your motion with a
motion detector
How your motion looks as a distance (position)-time graph
Materials
Logger Pro 3.3
motion detector (also called a sonic ranger)
Lab Pro
2 meter stick
Introduction In this investigation, you will use a
motion detector to plot a distance (position)-time graph of your motion. As you walk (or
jump, or run), the graph on the computer screen displays how far away from the detector
you are.
• "Distance" is short for "distance
from the motion detector."
• The motion detector is the origin from which
distances are measured.
• It detects the closest object directly in front of
it (including your arms if you swing them as you walk). The motion detector is sensitive
enough to measure first one leg then the other as you walk. Holding a large book or other
flat object in front of you will help you get smoother graphs.
• It will not correctly measure anything closer than
1/2 meter. When making your graphs don't go closer than 1/2 meter from the motion
detector.
- During the lab, any time the software asks if you want to
save the previous file click "No".
