The fall times t are measured for different heights of fall h. h is represented as the function of t or tē, so the distance-time law of the free fall results as h = 1/2 · g · tē. Then the measured values are taken to determine the acceleration due to gravity g.
1.distance time law for the free fall,
2.velocity-time law for the free fall,
3.precise measurement of the acceleration due to gravity for the free fall.
