1. the branch of physics that deals with the equilibrium and pressure of gases, especially air
Usage: technical; physics
2. the science of lighter-than-air aircraft such as balloons and airships
Usage: aviation; engineering

Examples

• The physics student studied aerostatics to understand how hot air balloons work.
• Aerostatics principles explain why helium balloons float upward.
• Early aviation pioneers relied heavily on aerostatics before powered flight.
• The meteorologist used aerostatics to predict weather balloon behavior.
• Aerostatics helped engineers design safer airships in the early 1900s.
• Understanding aerostatics is essential for atmospheric pressure calculations.
