This sounds like a homework question and we have some great resources that will be useful to you. We've got lots of them that focus on science. To access them you'll just need a library card and you don't have to be in the library to use them.
We do also have a number of science books in the library catalog including physics titles that will be useful.
If you would like to give us a call at 231-3750 we can get some more information and narrow down a particular resource for you.
