Today tried to measure acceleration due to gravity using motion of glider on an inclined plane.

Used the pickup i designed yesterday and photo-gate to measure acceleration. The results are very good and are in close agreement with theoretical calculations.

For motion on an incline acceleration along the inclined plane is g’ = g sin(theta) where (theta) is the angle on inclination. wrote a small python code using time measurement functions of ExpEYES library.

Used this code for measuring time…

import expeyes.eyesj

p= expeyes.eyesj.open()

a = p.multi_r2rtime(3)  # time for 1 cycle

b = p.multi_r2rtime(3,2)  #time for  4 cycles, 2 rising edges are skipped

print a

print b
