I am a 16 year old student who will be learning Physics next year. Before I actually start Physics in school, however, I want to have a basic or intermediate understanding of the subject beforehand. This is because I'm really interested in this type of science and I want to to impress my science teacher. I'm hoping to be borrowing some books relating to Physics in the oncoming weeks to help me learn.
Are there any resources online, Physics books, or exercises you guys can recommend to me? Also, are there certain terms or parts of Physics that I should start off with? (eg: the study of relativity)
