Pressure Part 2

[PDF of Slides]

Summary:

• Pressure differences lead to a net force, such as air resistance, buoyancy, and lift.
• Boyle’s law states that pressure in a gas increases as the volume is compressed.
• Pressure differences can be created by volume changes, as when we breath.
• The net force that draws air and objects into a vacuum is produced by the pressure difference between the vacuum and ambient atmospheric pressure (No “sucking” force).
