In free fall ,atmospheric pressure is also not present?i mean pressure is force per unit area ,so atmospheric pressure comprises force but?

in free fall there should be only gravitational force so atmospheric pressure is not present in free fall?

In free fall, atmospheric pressure still exists, although it is not directly felt or perceivable by an object or a person in free fall. Allow me to explain further:

In a free fall scenario, an object or a person is in a state of unimpeded motion under the sole influence of gravity. This means that they are accelerating downwards solely due to the gravitational force acting upon them.

Atmospheric pressure, on the other hand, is the force exerted by the weight of the air in the Earth's atmosphere on a given area. It is caused by the collisions of gas molecules with surfaces.

In free fall, the object or person is no longer supported by a surface, which means there are no collisions between the gas molecules in the air and the person or object to produce a feeling of pressure. However, the atmosphere is still present around the falling object or person, exerting its pressure on the surroundings.

So, while the sensation of atmospheric pressure may not be felt during free fall due to the absence of surface contact, the atmospheric pressure itself still exists as a result of the force exerted by the air particles in the atmosphere.
