I've been a physics professor at a large public university for 22 years, and have taught many introductory classes. (Yes, we are innovating our teaching with new techniques -- different question.)
You will never learn anything by reading books or watching videos. The only way to learn physics is by working problems. Hard problems, that make you sweat, and lots of them. But you can do this, and with the online resources you could be successful. Also you can pace yourself.
Ten hours per week is one class. Start with calculus based mechanics, (kinematics, Newton's laws, work-energy theorem, conservation of momentum, energy, and angular momentum.) If you can do the problems in a standard university physics book, then move on to electricity and magnetism. If you get through that and you don't think Maxwell's equations are the most awesome thing ever, then stop.
Also, never be afraid to learn your math in a physics course. It's the best way.
Good luck! You could really enjoy this if you will truly work at it for 10 hours per week as you suggest. But like dieting, you have to commit.
Yes, I'm probably misusing accepted terminology here. Finite time and finite planets, versus a non-finite space.
Finite time so far, but it will probably go on forever — the jury is still out.
But if the space is infinite, so probably too is the number of stars and planets. Otherwise there would be something special about space around here, and there is no reason to think we are special.
The Universe is NOT infinite. It is unimaginably, astronomically ginormous, but decidedly finite. If it was infinite, the Big Bang theory couldn't work.
That is not correct. The preponderance of data are consistent with an infinite flat universe and there is nothing about an infinite flat universe that is inconsistent with big bang cosmology.

But who on Earth would risk their life riding a bike, (...), when professional idiots kill bicyclists riding peacefully and safely?
Who would risk their life? That would be Spike. He's Spike Bike. He hates cars.
Why not use Node.js that has already got the wheel (JIT) rather than drilling holes in PHP to fit an axle?
Obligatory reference: ... all the complexities of assembler with the efficiencies of javascript.
