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 scientific principle?Based on Pascal's Law, enabling force multiplication through pressurized fluids
2. What is the primary branches?Hydraulics (liquids) and Pneumatics (gases)
3. What is fluid power and how does it work?Fluid power uses pressurized liquids or gases to create mechanical power. A pump builds the pressure, valves control the flow, and cylinders or motors turn that pressure into motion.
4. Why do we use hydraulics and pneumatics instead of just regular motors?Hydraulics use liquids that don’t compress, giving strong, steady force. Pneumatics use air, which is clean and safe in places where explosions could happen, so both give precise control and high power.

Pascal's Law: Pressure applied to an enclosed fluid is transmitted equally in all directions.
Hydraulic Cylinder: An actuator that converts fluid pressure into linear mechanical force and motion.
Fluid Motor: An actuator that converts fluid flow and pressure into rotational mechanical force (torque).
