    cheers, i was p happy to get it tbh, better than i expected. if i were u id know like a diagrammatic visualisation of it (then you can give examples from that), but know the general principles of propagation

    taking me well back dude, i kinda remember all that stuff. glad im not doing it this year bc i had a p packed hsc this year (for me at least). accelerating in it didnt help my final score (89) bc i was just kinda burnt out from it and didnt touch a book or anything for 3 weeks before the exam...

    how about back emf? could that be a point

    ok so heres the deal: if you stretched the wall out, the path of the ball would make a parabolic line against the wall, but horizontal (tangential) velocity is gonna be the same the whole way thru, just as in projectile motion. it is that tangential velocity that creates a normal (centripetal)...
