How people use the elasticity of air in their activities, give examples.

Air (in addition to breathing) is used by a person in many areas of his activity.

For example, many are familiar with the concept of “pneumatic equipment”. Air brakes are used in many parts of road and rail transport.

Airplanes and helicopters take off using the pressure difference above and below the wing (propeller blades).

The parachute also helps to safely descend from great heights.

All this is tied to the properties of air (pressure and elasticity).
