atmospheric pressure the pressure exerted by the atmosphere, usually considered as the downward pressure of air onto a unit of area of the earth's surface; the unit of pressure at sea level is one atmosphere. Pressure decreases with increasing altitude. ...
Pressure is the ratio of Force to the Area over which that force is distributed. The S.I. unit of Pressure is the "PASCAL" Pressure is a scalar quantity, it has no direction. When the area is small, a moderate force can create a very large pressure. This is why a sharp knife is ...

In science,pressureis a measurement of the force per unit area. TheSI unitof pressure is the pascal (Pa), which is equivalent to N/m2(newtons per meter squared). Basic Example If you had 1 newton (1 N) of force distributed over 1 square meter (1 m2), then the result is 1 N/1...

The pressure is a physical quantity that actually depends on both the force applied on a body and the amount of surface area involved in the process.The pressure is defined as the perpendicular force applied on a surface of an object or by an object per
