I'm new to this site. I don't know if this question even fits here, but here goes. So I want to learn physics, but my problem is I have very little to no knowledge on it. I am currently in 10th grade. I'm trying to understand what the teacher is talking about, but I'm having a very hard time. I think I understand the theory somewhat. My question would be How and where (as in a website) can I learn high school level physics? Preferably online. It's so much easier learning on my own for me. I would like to learn physics pretty much from scratch. It sounds really interesting and I'd like to learn more about it, but don't know where to start. I found MIT courses, unfortunately they are for undergraduates (we call it baccalaureate in my country). Are there any books or online courses I could start with?
