air is in a balloon
In a vacuum, where there is no air or matter, gravity still exists and continues to exert a force on objects. The absence of air resistance may result in faster acceleration of objects in a vacuum compared to in the presence of air.
The two ways the sun's heat is distributed are radiation and convection. Radiation is the transfer of heat energy through electromagnetic waves, such as sunlight reaching Earth. Convection is the transfer of heat through the movement of fluids, like warm air rising and cool air sinking in the atmosphere.
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
The contact force exists for every other force. It is responsible for the interaction between two objects that are in direct contact with each other. Examples include friction, tension, normal force, and air resistance.
The force of attraction that exists between any two objects is called gravity.

Boat or air plane
you breathing is out and in and that is the breathing is changes is
extract air bubbles from water
the air and oceanic plants
We know that gravity exists because we walk on our two feet and we do not float around in the air.
