FREE FALL APPARATUS
DescriptionExp-1 Determination of the value of ‘g’ using pendulum.
Exp-2 Determination of the value of ‘g’ by dropping metal ball using a solenoid.
Exp-3 Determination of the value of ‘g’ using 2L picket.
Exp-4 Value of ‘g’ using picket fence with ten slits.
Principle and Working :
Free fall instrument is the necessary instrument for the quantitative analysis of free falling objects. In the present setup, the value of “g” may be obtained with the help of photogate, ball, picket fence with ten slit and a digital timer by using the equation,
g= (vf2 - vi2 )/2s,
where vf final velocity, vi initial velocity and s distance between leading edge of first black strip & leading edge of last black strip.
