L2 physics after not doing L1
I've chosen to take L2 physics this year (along with my other two sciences) as it's a required subject if I want to look into studying optometry in the future (an option). I didn't do L1 physics and so I'm lowkey finding myself clueless as we go through the mechanics course.
I was part of the accelerate program at school in Y9 and so I have a very limited scope on physics, but we only covered the basic Y9/Y10 materials of forces and motion, light, and electricity (with forces and motion being my weakest point). My teacher isn't one who would be recommended as a good teacher, especially when it comes to cases like me who hasn't touched physics-related work since Y9, 3 years ago.
I think it's just all the concepts covered in the mechanics unit and the amount of formulas too which seem confusing and jarring to me. Is there any hope for me to progress well in physics despite having no prior knowledge of L1? Also, because we were accelerated, I never covered energy as well.
Can someone also explain to me about the different concepts in depth (I don't think my teacher does it enough). The only ones which I've got understanding on (due to completing L2 Calc) are:
- Graphs - Vectors and Scalors
- Kinematic equations
- Vector works (adding, subtracting)
Can someone please help me with these concepts:
- The different forces + in context
- Hooke's law (springs - energy?)
- Projectile motion
- Circular motion (centripetal force vs centrifugal force + calculating them)?
- Torque (single pivot, double pivot + equilibrium, centre of mass)
- Energy and momentum (kinetic, energy stored in spring, gravitational potential energy, conservation of energy, momentum + change of momentum, impulse, conservation of momentum)
I've really got to find time to go over everything that's been covered and make notes on them, but as we've only been doing our 2.1 reports portfolio these past few weeks + whole of last term, I've been focusing more on my L3 subjects and other internals so I haven't had any time to review physics.
