Cheat Sheet

[Infinity Plus]

I know our cheat sheets are really personal and specific to the individual but I was just hoping we could talk about some key stuff that would be good to include like definitions, tricky formula and just general dodgy stuff that could save us in the exam. Like for example I am going to put the full example for solving the angle of a banked curve when a body's traveling on a banked curve at a certain constant velocity (not just the tan cheat formula, the full force resolving parts,  in case they ask the question in parts). Anyways, post away.

my cheat sheet is really basic, not a lot of definitions so far (Young's + Photoelectric experiment, Lenz's + Faraday's law), ... and mainly just formulas.. but I just have a question about the cheat sheets.. are we allowed to bring four A4 sheets into the exam, glued back to back??

My personal tact has been to put down as many 'explain' questions as possible. They tend to be pretty tricky at times; missing small points can at times cost. Things like details on Young's experiment, Einstein's 'potential well' and how they support varying models of light is typically really good. As well as, Lenz's law and faraday's laws explanations.

Unfortunately, no. Two A4s stuck together double sided or one double sided A3

EDIT: woops I just realised I repeated what you said, guess that's what I get for being a terrible skim reader haha

righto! thanks for the clarification  also i looked at ur signature thingy, I hope you achieve 99 atar!

Banked curves are NOT on the study design anymore! Dont waste valuable space

Are you sure they are not on the study design? Could you provide a reference

From study design:
analyse the uniform circular motion of an object moving in a horizontal plane (Fnet = mv2/R) such as a vehicle moving around a circular road; a vehicle moving around a banked track; an object on the end of a string

Heyy guys I just got another question... Is weightlessness and true weightlessness the same thing??

Heyy guys I just got another question... Is weightlessness and true weightlessness the same thing??

Apparent weightlessness and weightlessness are different.
Apparent is when there is no normal force acting on you, eg freefalling. But gravity is still acting on you.

True is when there is no gravitational force acting on you at all, eg La Grange points.

I assume you mean the difference between Apparent Weightlessness and True Weightlessness. Apparent weightlessness occurs when the normal (or any reaction force) acting on the body is equal to zero, and therefore the body feels no resistive force and one feels weightless. True weightlessness can only occur if there is literally nothing near you with any mass such that the body experiences zero gravitational force on itself. As you may guess the latter is hard to achieve (maybe even impossible) because there is always something that does exert a gravitational pull on you even if it is very small.

Hope that helps

What is this La Grange points you speak of?

Ahhh sank you veri much guys! Is there way for me to give u guys the respect thingy, cos u guys earned my respect! 

[LazyZombie]

banked curves are on the study design o.o

If people start uploading their cheat sheets to the notes section, that would be great
I just uploaded mine, my have to go through moderation first before being available
