To get the acceleration of the object when ever falling down from a height in the presence of earth's gravitational field, which known as free of charge fall. Surroundings resistance is definitely neglected from this experiment. THEORY
As an object is introduced from a height from the beginning under the influence of the Earth's gravitational force, the object will always belong to a constant rate of acceleration. Unlike in space, exactly where object is going to just drift around after being released, target falling on Earth will always be ripped towards the surface by the law of gravity. Since the gravitational force with the Earth is actually the same for a particular place, the object is going to fall having a constantly elevating speed, that is certainly if air resistance is neglected. This kind of acceleration can be independent of the object's mass or height; this only depend upon which strength from the gravitational field. RAW INFO TABLE

JUSTIFICATION FOR QUESTIONS AND COMPUTATIONS
1) Doubt for metre rule
2. Half of the littlest division within the analog device
= 0. 01m/2
2) Uncertainty to get time taken
* Smallest division over a digital stop watch
3) Common time
sama dengan 0. 74+0. 75+0. 773
=0. 75s (for height=2. 200m)
4) Uncertainty intended for average period
=(maximum time-minimum time)2
=(0. 77-0. 74)2
=0. 015в‰€0. 02
5) Calculation of T2/s2
=0. 56 (for height=2. 200m)
6) Concern for T2/s2
= (maximum T2-minimumT2)2
= (T+uncertainty of T)2-(T+uncertainty of T)22
=(0. 75+0. 01)2-(0. 75-0. 01)22
= zero. 02s (for height=2. 200m)
Gradient of best fit line= 0. 601
Max. gradient= 0. sixty-five
Min. gradient= 0. 55
8) Concern of lean
=(max. gradient-min. gradient)2
sama dengan (0. 65-0. 55)2
= 0. 05
