i didnt realise u posted b4 meTennille said:I'm looking at the 2002 formula sheet. When I mention the sections, I'm going down the page.
The first section is for waves, second section is for electricity/motors and generators, third is motion, fourth is mainly for astrophysics, fifth is for motors and generators, sixth is for space, seventh is for from ideas to implementation and the last three sections I'm not sure about.
Haha..no problems.spank_meh said:i didnt realise u posted b4 mesorry hahah
Captain Gh3y said:Warning about 'preliminary' formulas:
There are (and this confused me often) a lot of formulas that are VERY useful in the HSC course, that are all located on the preliminary section and may be overlooked. They are:
E = F/q. This rearranges to F = qE,which you will need for forces on Cathode Rays in Ideas to Implementations.
F = ma, which is fairly obvious, but it can be used in Space for calculating Acceleration due to gravity, or in Ideas to Implementation to calculate the acceleration on a particle in a field.
F = mv²/r, centripetal force is part of Space. This is used in the derivation of Kepler's Law and in calculating orbital velocity.
Ek = 1/2(mv²) which again is pretty obvious, but it's used in space for calculating Escape Velocity, and quite possible in Ideas to Implementation and Quanta to Quarks for calculating the energy of various particles.
W = Fs, not used directly but it leads to Ep[/b] = mgh, which is NOT on the formula sheet, but is in the syllabus in Space.
p = mv or I = Ft may be useful for rockets in Space, if only to understand the concepts better.
