This page introduces the concept of pressure and focuses on solid pressure.
Definition: Pressure is the net force acting perpendicular to a surface divided by the area of that surface.
Pressure is denoted by the symbol P and measured in Pascal (Pa) in the SI system. Other units of pressure include atmosphere (atm), bar, and torr.
Highlight: Pressure is a scalar quantity.
Solid Pressure: Solid objects exert pressure on surfaces due to their weight. The formula for solid pressure is:
Formula: P = F / A
Where: P = Pressure F = Force (weight of the object) A = Area of contact
Example: If three objects with different weights (F1 = 1, F2 = 2, F3 = 3) are placed on surfaces with the same area, their pressures will be in the ratio P1 : P2 : P3 = 1 : 2 : 3.
The page also mentions that solids transmit forces in the same direction and magnitude as applied.
This page delves into the concept of liquid pressure and its properties.
Formula: P = h * d * g
Where: P = Pressure h = Height of the liquid column d = Density of the liquid g = Acceleration due to gravity
Key properties of liquid pressure:
Highlight: Liquids take the shape of their container and exert pressure on all surfaces, including the sides.
The page provides examples of pressure calculations in different shaped containers and introduces the concept of pressure at different points within a liquid.
Example: In a U-shaped tube with two different liquids that don't mix, the heights of the liquids will be inversely proportional to their densities when in equilibrium.
This page introduces Pascal's Principle and its applications in hydraulic systems.
Definition: Pascal's Principle states that pressure applied to an enclosed fluid is transmitted equally throughout the fluid without any loss.
The principle is illustrated with diagrams showing how pressure is transmitted in enclosed systems.
Example: Hydraulic lift systems use Pascal's Principle to multiply force. A small force applied to a small piston can create a much larger force on a larger piston.
The page also covers:
Highlight: In hydraulic systems, the ratio of forces is inversely proportional to the ratio of areas of the pistons.
This page focuses on gas pressure and introduces the concept of atmospheric pressure.
Definition: Atmospheric pressure is the pressure exerted by the weight of the air in Earth's atmosphere.
Key points about gas pressure:
Vocabulary: Barometer - An instrument used to measure atmospheric pressure.
The page discusses Torricelli's experiment, which first measured atmospheric pressure:
Pressure in physics is a fundamental concept that applies to solids, liquids, and gases. This guide explores:
