Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the operating principle?Conversion of compressed air potential energy into mechanical work via pneumatic motors
2. What is the key performance metric?High power-to-weight ratio, enabling compact and potent tool designs
3. How do pneumatic tools move?They have a motor that can be a vane, piston, or turbine. The air pushes on the motor and makes it spin or move back and forth.
4. Why are pneumatic tools safer than electric ones?They have no electrical sparks, so they are safe in places with flammable gases or dust. This makes them useful in factories and oil fields.

Fluid Dynamics: The study of how fluids (like air) move and exert forces.
Pneumatic Motor: A device that converts compressed air energy into rotational or linear mechanical motion.
Power-to-Weight Ratio: A measure of a tool's power output relative to its mass, indicating efficiency and portability.
