Pre-transposed formulae
« on: May 24, 2011, 05:31:50 pm »

Does anyone have a collection of all the good pre transposed formulae that can be directly applied to questions. I have for e.g all of the gravity equations pre transposed. I was wondering if anyone had any other ones which could be used for e.g for projectiles or whatever.

Also does anyone have a copy of the 2010 NEAP diagnostic test for electronics and photonics.


Thanks!  :D

My teacher actually gave us some useful projectile motion formula's today (E.g. finding highest point, finding the horizontal point at any given time and finding the range). Do you want me to scan them on the computer? and if so, do you want me to scan the formula's and diagrams, or just the formulas?

Also, do you know of the formula PEs = F^2/2k? (PEs = spring potential energy, f is the force, and k is the spring constant)

I havn't heard that.

Yeah scan me all the good formulas you got. That'd be appreciated.

Yes please!

I saw some kid at school have all these pre transposed ones for energy aswell. I think he goes TSFX lectures and they give him all these pre transposed formulae.

the only ones i know are:
Kinetic Energy: (where p is the momentum, and m is the mass) -> Found that formula on here :P
Spring Potential Energy:

I know this is a stupid question, but do you know the conservation of energy "equation"?

Edit: More formula's that i just found:



I can't remember if this is in the book either, so here it is:


where P is the power, F is the force, v is the velocity
