I think this is like asking what does a tree look like when nothing is looking at it. I am guessing what something looks like will depend on how we decide to 'look' at it.
I am going to be taking the PRAXIS II physics exam (the two hour one) in a month.
Have anyone taken it before?
I am quite worry about it. I don't feel like I understand anything. How should I prepare for it? Is there any books I should get?
I appreciate any suggestion.

I have a question.
If a person is in an elevator, and the elevator is accelerating down faster than the gravitational acceleration on the person, then what would happen to the person? Is he going to hit the ceiling? Does the answer have something to do with air?
