I've got:This is good Idea, plus what we did for detailed study, relativity. Also momentum is conserved in a closed system, loss of kinetic energy in a collision deems it to be inelastic.

Same and what do you mean by "smoothing"?It's in the further electronics detailed study - the process of using capacitors to absorb excess electrons from the circuit when voltage is heigh, and release when voltage is low.

I thought we don't need to worry about photostransistors?You don't need to worry about transistor circuit however (as far as i'm aware) there may be a question comparing Photodiodes/Phototransistors and LDRs.
Basically they fit between LDRs and Photodiodes in terms of response time and are able to detect really low levels of lights and respond to allow current to flow.
I may be wrong about it being on the course - but our teacher taught us it so better safe then sorry.

There was a question in a practice paper asking you to define an 'analogue system'. Might be worth throwing in because I'd never even heard of that term before.
There's also digital system =/
And all i have on my cheat sheet are the basic pointers for apparent weightlessness and carrier wave.
Post by: ks04 on June 06, 2010, 01:55:38 pm
vs analogue systems are varying levels - think light getting a light getting darker and brighter depending on the signal i.e a sin wave (though does not have to be uniform)

Digital - Discrete levels of signal. Generally only two - 'On' or 'off'.

I threw in the definition of digital system following my analogue definition.
I've been accumulating my cheatsheet since the beginning of the year, it's just a swamp of equations that I'll never use.

I haven't even made one yet.. Just written down 5-6 definitions...
lol same.....itute :P

Can anyone be kind enough to upload one, i want to skim over one to get a few ideas. I tried to scan mine but you cant read it...If you dont feel like sharing got any others on the net you can direct me too? Cheers guysI'll upload mine in the morning when i have access to a scanner.

Can't imagine it would, I just scribbled down a couple of extra things at the top and bottom of the page.

As long it's a cheat sheet that followed the rules from VCAA.

Here be my cheatsheet.
Not that it's likely to matter but I noticed that for Kepler's law you have
I believe the radius is meant to be cubed.

You're quite right, cheers! We're all human.

Here be my cheatsheet.tht is the worst fuckin cheat sheet i have ever seen
shutup.
Post by: ks04 on June 07, 2010, 04:47:14 pm
No problem. Unlikely it will be used, lol, but anyway. Do you guys think you'll end up using it at all?I doubt I'll use most things on my cheat sheet, but it came up in an old exam I was doing, figured better safe then sorry!
For me making the cheat sheet was more an introduction to revision then anything, bring back all the old stuff which is burried away in the head!

I've used a few times, I hope so, and I hope there's heaps of gravitation questions...I love them, just plug and play lol.
