Freely Falling Objects Video Lecture - JEE

freely falling objects and acceleration
due to gravity all objects when dropped
from a height fall towards the earth
this happens due to the gravitational
force exerted by the earth on the object
suppose you drop simultaneously a small
stone and a cotton ball of the same size
from a height which of the two will
reach the ground first we see that the
stone reaches the ground earlier than
the cotton ball so we may falsely
conclude that the heavier objects fall
faster than the lighter ones that is the
acceleration produced in heavier objects
is more than in lighter objects Galileo
showed that all bodies whether light or
heavy fall at the same speed towards the
earth Galileo explained that the lighter
bodies fall at a slower rate due to the
resistance of the air later robert boyle
proved this experimentally he placed a
coin and a feather in long glass tube
and evacuated it with the help of a
vacuum pump robert boyle observed that
when the tube was inverted both the coin
and the feather reached the bottom of
the tube at the same time thus he
concluded that the acceleration produced
in all the freely falling bodies is the
same and does not depend upon the mass
of the falling body
