Here are all the formula that you are required to know for GCSE Physics. I will devide them between P1-7 but they are still useful if you are not on the OCR.

P4 Formula
Average Speed - Distance travelled / time taken
Change of Momentum - Force x Time for which it acts
Momentum - Mass x Velocity
Velocity - Momentum / Mass
Work done - Force x Distance moved in direction of force
Gravitational Potential Energy - Weight x Vertical height differance
Kenetic Energy - 1/2 x Mass x (Velocity)x(Velocity) - [I mean squared but the computer wont let me do the little 2]
9 of 15
P5
10 of 15
P5 Formula
Resistance - Voltage / Current
Power - Voltage x Current
Power (work done) - Power x Time
Energy Transfered - Power rating x Time
% Efficiency - Energy transfered to the desired location / Work done by the appliance
Transformers - Voltage of secondary coil / Voltage of primary coil = Number of turns on the secondary coil / Number of turns on the primary coils

P6 Formula
Wave Speed - Frequency x Wavelength
13 of 15
P7
14 of 15
P7 Formula
Power - 1 / Focal Length
Magnification - Focal Length of Objective lense / Focal Length of Objective lense
thanks for the help :) it has helped me a lot with my revision...
one problem, you need to change the last slide, its:
focal length of the objective lens/focal length of the eyepeice lense
other than that its a great help
thanks :)
