Reddit reviews Conceptual Physics: The High School Physics program

If you're not familiar with physics at all, then i'd try picking up a textbook that's devoted to the conceptual side of physics with a little algebra here and there. For example

Once you have a basic understanding of that and you're familiar with calculus, try a more rigorous college-level calculus based physics text. Example

Personally, i'd stick with textbooks since i see them as a very effective way of learning a subject, but i understand everyone learns differently. Whatever works for you.
