What is Pascals Law?
E=mc2
Energy = mass times speed of light squared
V=d/t
Velocity = displacement over time

Which is a hydraulic system?
One that uses air, like a dentist's tools
One that uses liquids, like a car lift
Which is a pneumatic system?
One that uses air, like the barber chair
One that uses liquid, like a firehose
How does a car lift work?
A small amount of force is used on the large piston that then pushes the small piston up because the liquid is compressible
A large amount of force is used on the large piston that then pushes the small piston up because the liquid is incompressible
A small amount of force is used on the small piston that then pushes the large piston up because the liquid is incompressible.
A large amount of force is used on the small piston that then pushes the large piston up because the liquid is compressible.
