For a spinning object does the drag act against the direction the object is rotating?

What you just said is an explanation of lift using Bernoulli's principle. Another explanation is using Newton's 3rd law which is what I'm talking about.

Ok so I just read this statement as part of an explanation of list using Newton's 3rd law "The amazing thing about wings is that because they are flying through air which is a fluid, the top of the wing deflects air down as well as the bottom of the wing." What I don't understand is how...

I understand why it turns to travel in a circular path. But why does it flatten out from vertical when you throw it.

I wasn't actually trying to calculate it. Just making sure I understand Newton's 3rd law. :smile:

Ok so you push a box forward and the box exerts a force of friction backwards Would the reactionary force to the friction on the box (the ground pushing the box backwards) be the force of the box pushing the ground forwards
