"Corkscrew" vs side top loop

So the string would be the vertical axis, but the ball is spinning on a horizontal plane?

I thought you would be able to figure out what the axis was from the video. But, I guess not.

Look at the definition I wrote already from the dictionary.

Stop pretending you know. It is better to say, "okay guys, for some reason I just don't get what the word axis actually means."

There is nothing wrong with not understanding something. But don't try and pretend you do because you are way off.

Here is the definition:

Definition: "Axis: an imaginary line about which a body rotates. The earth revolves on its axis once every 24 hours."

That comes from Apple's dictionary on this computer.

Let's see if some images can do what words have not been able to do:

Do any of these make it more clear what an axis is.

AN IMAGINARY LINE AROUND WHICH A BODY (in our case a ping pong ball) ROTATES.

So if the ball was spinning very fast and you could see the label of the ball spinning, and say, the axis was vertical and the label was at the top of the ball, the label would be just spinning around on top and you would kind of be able to see where the axis of spin was.

I too had a different idea of the definition of axis. Worst part of this is I've aced both my physics classes.

I'm better with memorizing formulas and applying them to a word problem than visualizing it I suppose
