What is the difference between What is the difference between Hydraulics and Pneumatics?Hydraulics and Pneumatics?

Answer:Answer:

Hydraulics uses Hydraulic oil and Hydraulics uses Hydraulic oil and Pneumatics uses airPneumatics uses air

Why are Pneumatics and Why are Pneumatics and Hydraulics importantHydraulics important

Pneumatics and Hydraulics are Pneumatics and Hydraulics are important because they allow us to important because they allow us to operate machinery that is capable to operate machinery that is capable to lifting heavy objects or to move lifting heavy objects or to move machinery into precise positions. machinery into precise positions. Examples of hydraulics operations are Examples of hydraulics operations are excavators or front loaders. excavators or front loaders. Examples of Pneumatics are air bags Examples of Pneumatics are air bags on a vehicle.on a vehicle.
