Summary:

• Gases (like air) and liquids (like water) are called fluids because they flow.
• Pressure is related to force and it’s useful for understanding motion involving fluids.
• Pressure is defined as the amount of force per area, such as pounds per square inch.
• The pressure in a fluid increases with depth due to the weight of the fluid.
• Pressure differences in a fluid disappear during weightless free fall.
