I could not help but notice in my daughter's first year university physics text what I think is misconception of Bernouilli's principle.
The illustration of Bernouilli's principle is a truck with a tarpaulin on the box. When the truck speeds down the highway, the tarp lifts. This is supposed to illustrate Bernoulli's principle.
The problem here is that the air is not moving. The truck is. So how can this be an illustration of Bernoulli's principle?
The same misconception frequently occurs with airplane wings. They do not create lift due to Bernoulli's principle. They create lift due to turbulence of the air flow.
