In moving about the only stuff that really carries along is Newton's laws, law of conservation of momentum, and the basic motion formulas (e.g. v = u + at), which derive into the projectile formulas in year 12.
The year 12 content for Space was easier to understand I think (maybe except the relativity stuff which is a bit abstract) but I don't know why it was just easier to understand. For example the definitions are easier - weight = force on a mass in a gravitational field - it's pretty direct and the concepts some of them are rote learning - e.g. Newton's concept of escape velocity.
For now we're doing motors and generators and this one was harder but this is really direct so once you understand it then you pretty much are good with it because it's just some hand rules, laws (e.g. Faraday and Lenz) and some concepts (e.g. eddy currents or motor effect) which form the fundamentals of the whole topic basically and are asked in every HSC paper in one way or another.
I definitely found the harder applications of moving about questions and also waves (the world communicates) as well as electricity harder than the year 12 content. The electricity in year 11 is harder than the year 12 electricity stuff ironically... probably because of the current/resistance/voltage problems.
