what is that?It is Cowpea
Electricity is pretty fun imo, doesn't require that much memorisation either. Most of the stuff is very logical, so it's easy to remember.

^ oh is it lol, that's cool then. That's why I love physics right now. No memorisation involved yet.

It's good to memorise the formulae.
But, in the end, you do get the formulas on an extra sheet of paper in the test.

LOL, when in doubt, derive the formulae.
This. Especially comes in handy for the space HSC topic - half the formulas don't get given to you on the formula sheet. You have to memorise them or derive them.

^ I was kidding, I mean no one is expected to be able to derive the formula for centripetal acceleration in uniform circular motion let alone do it in an exam lol. But yeh, in year 12, there are people who simply memorise formulas for say maximum height reached by a projectile when they can do it quite quickly simply using the basic kinematics formula i.e. v=u+at, S=ut+0.5at^2. Doing this you are at much less of a risk in losing marks.

E.g. in one of the outcomes for space, you need to be able to derive Kepler's law of periods by equating centripetal force and gravitational attraction force to get the formula for orbital velocity then making v = circumference/period and solving it through. Not difficult but still need to know how to derive it.
you see, just seeing this 'thing' on physics drives my head in... you all do ext. maths, yes?

yes, but the maths in physics is a lot easier. as long as you can get your head around the concepts in physics, you should be fine. and if you get stuck, BOS is here to help

hahaha I dropped it lovelyyes, but the maths in physics is a lot easier. as long as you can get your head around the concepts in physics, you should be fine. and if you get stuck, BOS is here to help
... maths ext and physics are on the same sorta 'wavelength', excuse the pun its alright. just do the subjects you enjoyhahaha I dropped it lovely

The actual mathematical skills required is at maximum, 2U level.
True. Doing 2U helps - like after doing exponentials and logs in 2U, it makes calculating pH in chem seem super easy.
