Pressure Study Guide

Definition: Pressure is the amount of force applied to a given area.

Units of Pressure:

There are several units of pressure, including:

• Pascals (Pa)
• Atmospheres (atm)
• Pounds per square inch (psi)
• Millimeters of mercury (mmHg) or Torr

Formula for Pressure:

The formula for pressure is:

Pressure = Force / Area

Factors Affecting Pressure:

Several factors affect pressure, including:

• Force applied
• Area over which the force is applied
• Depth (in the case of fluid pressure)

Applications of Pressure:

Pressure has numerous applications in everyday life, including:

• Weather systems and atmospheric pressure
• Hydraulic systems
• Blood pressure in the human body
• Scuba diving and the effects of water pressure

Pressure in Fluids:

When a force is applied to a fluid, it creates pressure. The pressure exerted by a fluid depends on its density and the depth of the fluid.

Study Tips:

When studying pressure, it's helpful to:

• Understand the relationship between force, area, and pressure
• Practice using the pressure formula in different scenarios
• Explore real-life examples of pressure and its applications
• Review the units of pressure and how to convert between them
