Mini-Quiz: Fluid Friction

by Ron Kurtus

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

1. How can friction slow down a speeding boat?

Fluid friction from the water against the moving boat surface hinders motion

Fluid friction actually speeds up the boat

Friction does not apply to boats

2. Why does lubrication help reduce sliding friction?

It actually increases sliding friction

Fluid friction is less than sliding friction

Lubrication turns sliding friction into static friction

3. What is an example of a fluid moving over a different fluid?

Bubbles in boiling water

Water flowing over a layer of grease

Sliding on a greasy surface

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.

Be persistent
