Does anyone have a list of or can list the experiments they can ask us to describe?
Already mentioned earlier somewhere, it is: SHM, specific heat capacity and Brownian motion.
SHM - know what it is and how to interpret what's going on, including energy exchanges. SHC - know how to measure it (by heating solid/liquid) in a circuit and then calculate it. Brownian - well it's just proof of random motion; how? Well putting jar of gas under a microscope with light shining on it so one can see the motion of gas molecules which is random proves it is hitting air particles.
If the gravitational force due to a planet was the only force acting on a satellite, could you use a=v^2/r to calculate g, by doing g=v^2/r? I'm slightly confused, is g equal to a when the gravitational force is the only force acting on an object?
June 2012 Question 4bi) A to B: I was always taught when the temperature increases, only KE increases not the PE, but in the markscheme you are not awarded a mark if you put that only KE increases.

OCR man...
You were tough wrong when T increases both KE and PE increase. When change of state occurs KE stays the same only PE increases
I'm pretty sure you're actually supposed to draw them all to the centre of the planet where they meet at a point.
No, in the mark scheme under guidance for examiners it says something along the lines of "judge by eye that all lines meet in at one point in the centre
