When your friend squeezes your arm, you feel pressure that's because molecules collide with each other and things like your arm, the ground, or a tree.
The most basic change in pressure is the twice daily rise and fall in due to the heating from the sun each day, around 4 am/pm the pressure is at its lowest and near its peak around 10 am/pm.
Press the air pressure gauge evenly onto the valve stem and record the reading given if there is a hissing sound, the gauge is not tight or even enough for an accurate reading.
Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of earth (or that of another planet) in most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure.
Air pressure (or atmospheric pressure) refers to the weight of the atmosphere covering a certain area it can also refer to the whole weight of the earth’s atmosphere over the planet.
Air′ pres`sure n the force exerted by air, whether compressed or unconfined, on any surface in contact with it [1870–75] thesaurusantonymsrelated wordssynonymslegend: switch to new thesaurus noun 1 air pressure - the pressure exerted by the atmosphere atmospheric pressure, pressure gas pressure - the pressure exerted by a gas barometric pressure. By definition, atmospheric or air pressure is the force per unit of area exerted on the earth’s surface by the weight of the air above the surface.
Air pressure basically refers to the volume of air in a particular environment, with greater volumes creating higher pressures on the earth's surface, for example, it is known as atmospheric pressure and refers to the weight of the earth's atmosphere pressing down on everythingchanges in pressure can impact the temperature, weather patterns, and cause physiological problems for people and. What is air pressure introduction what is air pressure air pressure is the weight of air molecules pressing down on the earth the pressure of the air molecules changes as you move upward from sea level into the atmosphere. Air pressure definition, the force exerted by air, whether compressed or unconfined, on any surface in contact with it see more.

Pressure (symbol: p or p) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure various units are used to express pressure some of these derive from a unit of force divided by a unit of area the si unit of pressure, the pascal (pa), for.
