| Man Jumping From A Flying Plane. |
What would
happen if you jumped from a flying plane? Obviously, you will fall down on the
surface of the earth. Just fell that moment when you are falling from a flying
plane. Will you feel weightlessness or
something like that? Sounds crazy! Let’s crack it.
So, fist of
all, what is free fall?
If the body
moves under the influence of the gravity alone, the motion is called “free fall”
or in other simple words, when a heavy ball of iron is released from a height,
the ball is under the action of gravity (attraction of the earth) alone. Of
course, there exists resistance due to air friction. If the shape of the body
is spherical and its size is small, the air resistance is negligible as
compared to the gravity. As a result, the motion of the body can be considered
as a free fall. In fact, body falling in vacuum is the free fall. The best
example of free fall could be a body falling onto the surface of the moon. It
is because; the moon has no atmosphere around it.
In the case
of jumping from a plane without a parachute is defiantly a very bad idea. But
if you jumped you will fell weightlessness (not Truce Weightlessness) you fell
that you are not being attracted by any force.
However, you are the
only in free fall if the gravity is the only force acting on you. You do not
experience this however, as your inertial frame is traveling with you and
gravity exerts the same force on each and every point. You will however feel
the effect when you eventually hit the ground if not, in orbit or heading into
interstellar space.
