This
report is about the Galileo’s famous gravity experiment about the gravity. 400
years ago, he said that the velocity of heavy ball and the feather will be same
when there is no air resistance between them.

Abstract
of Galileo’s Famous Gravity Experiment
In
this report there is discussion about the famous experiment of Galileo that is
about the velocity of heavy and light object when it is thrown from the certain
height. The hypothesis that Galileo has suggested is that velocity of heavy
object and lighter object will be same when there is no involvement of the air
resistance. This experiment will be performed through the help of bowling ball
that as the heavy object and on the other hand feathers are taken for the
lighter object.
Introduction
of Galileo’s Famous Gravity Experiment
In
this report there will be complete justification of the hypothesis of Galileo
that is about the effect of gravity when there is no air resistance. In the
past the Italian scientist Galileo was involved in given the hypothesis about
the air resistance. He said that there the heavy object falls faster than
lighter objects. This is just because of the air resistance between them. If
there is no air resistance between them then the heavy and lighter object will
fall at the same time. For proving his hypothesis there is need of experimental
results. In this report there are some experimental results that will help to
prove this theory in proper way.
Theory
of Galileo’s Famous Gravity Experiment
In
the past one of the most popular Italian scientist has proposed one of the most
famous hypothesis about the gravity and air resistance of the two sphere that
have two different masses. Means that one ball is heavy and the one is light.
He throws these balls from the leaning tower of Pisa. It can be seen that both
bowls has different masses so they depend upon the time. Then after this
experiment he has proposed that the object will fall on the ground at same
velocity and acceleration when there is no involvement of air (Hilliam).
Procedure
of Galileo’s Famous Gravity Experiment
For
proving his hypothesis an experiment is done. The apparatus used for this
experiment are bowling ball, feathers and stop watch for measuring the time. The
mass of the feature and ball is not same. Then after this both of these object
were thrown on the ground, and the time will be measured. Then after this the
air form the room will be removed properly. The room will be completely full of
vacuum. There will be not a single sign of air in the room. Then after this
both of these object will throw again on the ground.

This
figure is the relationship between the time and velocity of the free falling
object

This
figure is the relationship between the time and distance of the free falling
object. This shows that there is exponential relationship between the time and
distance of the free fall object. For this there is use of trend line of
polynomial.
Discussion
on Galileo’s Famous Gravity Experiment
The
results show that there will be effect of any mass of the body when there is no
sign of air. Both object will fall on the ground at same speed.
Conclusion
on Galileo’s Famous Gravity Experiment
Summing
up all the discussion from above it is concluded that the hypothesis that was
made by Galileo was completely correct. That has been proved in this
experiment, the velocity of both bodies is same when there is no any sign of
air between them. Both heavy and light object will fall on the ground at the
same time when there is air is present.
Reflection of
Galileo’s Famous Gravity Experiment
The
present experimental work increases conceptual understanding of Galileo famous
formula of velocity about the heavy and the light objects. According to
experiment, it was evident that velocity of lighter and heavy objects will be
same in the absence of air resistance. The velocity of falling objects also
depends on the shape and size regardless of air resistance. The results show
that with increasing time duration for the moving objects the velocity and the
distance increase for the freely falling objects. The polynomial trend was observed
for falling massive bodies. The experiment provides additional analysis that
proves accuracy of Galileo hypothesis.
