Aim of Experiment
• To observe and analyze the motion of a free-falling body.
• To determine the relationship between time and acceleration due to the
gravity of the falling body.
• To determine if all objects can fall with the same constant acceleration in
the absence of air and other resistance.
Apparatus
• We use in this experiment:-free fall apparatus, spark counter, meter stick,
and metal ball.

Procedure
1:We arrange for one student to count the seconds.
2:another student used a metal ball in the instrument that I mentioned in
the diagram we were having meter stick on that instrument we did that
several times using the meter stick, metal ball, and others we knew that
when we were decreasing the length the time was also decreasing.

Results, Discussions and Conclusion
With this experiment we found out that as we decreasing the length, the time
also decreasing. And it was very interesting experiment.
