Get the items needed and determine acceleration due to gravityÂ
using SOUND OSCILLOSCOPE
Inference: The falling time depends on height the object from the ground.
Hypothesis: The higher the object being released, the longer the falling time.

DISCUSSION
Compare the value of g from this experiment with the standard value of g. Why is there a difference between the two values?
Research found out that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles. Discuss why there is a slightly difference ?
State and explain one precaution that needs to be taken to improve the accuracy of the results of this experiment.
Identify the source of error(s) and give suggestion to overcome the error(s) stated.
What conclusion can be drawn from this experiment?Â
