The ski glide project

The experiment:

This experiment was done with 4 different pairs of skies with different grind, measuring the time between two sticks in an constant angled downhill. A skier with initial velocity started 5 meters higher up the hill than the first stick where the time recording started. The time was measured between meter 5 and 30.

The measured time at 5 meters shows that the velocity was constant.

Name of ski	Time 5m (s)	Total time (s)	Speed (m/s)
100	1.31	7.01	3.81
101	1.31	6.97	3.86
102	1.33	7.12	3.75
103	1.36	7.30	3.64

The wheater on the test day was sunny and with a temperature around 40F/4.5C.
