Mini-Quiz: Applications of Fluid Principles

by Ron Kurtus (updated 9 February 2022)

Take this Mini-Quiz to check your understanding of the lesson material.

1. If the area of the larger piston in an hydraulic device doubles, what happens to the force applied to that piston?

It stays the same

It doubles

It is cut in half

2. How can a plane fly up-side-down?

It can only be done in the movies

By flipping its wings inside-out

By flying at a slight upward angle

3. Why doesn't a fluid have a rough surface like a solid?

It does, but you can't see it

A fluid's surface has no distinct shape

Fluids are all slippery

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
