Could someone help answer this question from the AQA A-level Year 2 Physics Oxford text book:
"State whether the damping in each of the following examples is light, critical or heavy:
ii. oil in a U-shaped tube displaced from equilibrium the released"
The book says that the answer is heavy however I do not understand why this is, oil has minimal friction so surely the damping would be light?

Motion in oil is heavily resisted due to its high viscosity, so you could re-label 'friction' here.
Note there are 4 main types of friction: static, sliding, rolling, fluid. Resistance will do.

I suspect you are confused with something – oil can help to reduce friction between two solid surfaces but it does not flow smoothly which is a property known as viscosity.

https://en.wikipedia.org/wiki/Viscosity
If you compare the viscosity value for oil and water (from the above websites), you would realize that water has a much smaller value than that of oil
From your daily experience, you should be able to come to realize that oil tends to flow slower than water.
