Transformers is likely to come up for a P5 6 -mark.

Anyway, I'm giving up on P5. I get it, sort of but it's frustrating me so I'm going to move on to some P6 which will make me a lot happier :biggrin:

What's the difference between a reaction force and interaction pair also do distance time graphs show direction if its going downhill I.e back to the start


The reaction force is created when an object is put on a surface. It is basically the surface pushing up with an equal force.
An interaction pair of forces involve two different objects. They are equal in size, and opposite in direction. The object pushing down on a surface, and the reaction of the surface is an interaction pair.
Idk if that made sense, but I hope it helps you!
Hey, do you guys have any revision tips for me? I don't know how I should revise. I have done pretty much everything but need to go over it?
Are there any things I could do to guarantee that I know everything?
Thank you very much for your help:smile:)

Displacement has direction. (E.g -10m/s is just in the opposite direction.)
I really hope P456 goes as well as B456 and C456 :P

Displacement is how far you've moved in a straight line. Distance is your real distance. If you finish where you started, your displacement is 0. Your distance is the total distance of the journey there and back.

I just had to go in for chemistry, although I just played on my phone the entire time.

It's not P4 or P6 that everyone's worried about though, it's the evil circuits!

Ah k, hah :smile:
Yep :yep: I'm worried about the whole thing :tongue: and I still haven't started p6 :/ how you progressing?
Can someone clear this up please?I really don't know :frown: :confused:
If mains electricity is induces and it is AC, how is it transported to houses and such? Wouldn't the current just turn back and forth and never actually go anywhere as opposed to direct current which goes in one direction?
How's revision going since I last posted people?

I've just finished notes of P6 (such an awesome module in an awful paper) and finished reading P4, I'm going to make notes on it after a short break. I used to hate P4 but it's actual all-right..just mathsy with simple maths?! Yay :biggrin: Then after, at around 6 I think I'll crack open P5 again and go over crap.

As soon as this exam is over tomorrow, I swear I'm going to be SO happy. The exam I'm dreading will be OVER!
