Definition
- Adjective:
- Pneumatic: Relating to or operated by air or gas under pressure. This describes devices, tools, or systems that use compressed air to function.
- Aerodynamic: (Note: This is a distinct, advanced meaning. The primary meaning in the given context is "pneumatic"). Relating to the properties of a moving object interacting with air, concerning forces like drag and lift.
Usage Examples
Adjective (Pneumatic):
- Công cụ này chạy bằng hệ thống khí động. (This tool runs on a pneumatic system.)
- Anh ấy sử dụng búa khí động để đóng đinh. (He uses a pneumatic hammer to drive nails.)
Adjective (Aerodynamic - Advanced):
- Thiết kế khí động của xe giúp tiết kiệm nhiên liệu. (The car's aerodynamic design helps save fuel.)
Advanced Usage
- In technical/engineering contexts: The term is almost exclusively used to mean "pneumatic," especially when referring to industrial tools, machinery, or control systems.
- Đường ống khí động (Pneumatic pipeline)
- Xi-lanh khí động (Pneumatic cylinder)
Variants and Related Words
- Khí động học (Aerodynamics): The study of the motion of air and other gases and the forces acting on objects moving through them.
- Khí động học là một nhánh của cơ học chất lưu. (Aerodynamics is a branch of fluid mechanics.)
- Khí nén (Compressed air): The pressurized air used in pneumatic systems.

Notes on Different Meanings
- The core and most common meaning of 'khí động' in Vietnamese, especially in technical and industrial contexts, is pneumatic.
- The meaning aerodynamic is a specialized, secondary meaning derived from the compound term 'khí động học' (aerodynamics). When used alone to mean "aerodynamic," it is often within specific technical discussions about vehicle or object design.
