Evidence of Speed
A TRACKWAY can be divided into three sections: The PACE, the distance between the right and left foot; the STRIDE, the distance between two successive steps (right-right, or left-left); and the GAUGE, which is the width of the tracks, telling how close the legs were together. Measure toe to toe.
Materials
1. On sand (or other good footprint area) measure out 5 meters. 2. Walk or run across this area timing how long it takes to go the 5m. 3. Measure your foot length and multiply by 4 to get the hip height. 4. Measure your stride from the footprints. 5. Calculate your speeds (on data table below). 6. Compare the two methods of calculation
Formula for direct measurement: speed = = __________meters/second Formula for Indirect measurement: (Alexander's) NOTE: g= 9.8 meters/second² speed= ___________meters/second |
