I know it's really hard but here are all the ones that you need to know (picked them out from the revision guide =P)

Speed = Distance/Time

Acceleration = Change in Velocity/Time Taken

Weight = Mass x Gravitational Field Strength

Force = Mass x Acceleration

Work Done = Force x Distance

Kinetic Energy = 1/2 x Mass x Velocity2

Momentum = Mass x Velocity

Force Acting = Change in Momentum/ Time Taken for Change to Happen

Resistance = Potential Difference/ Current

Energy = Power x Time

Power = Voltage x Current

Total Change = Current x Time

Energy Transformed = Charge x Potential Difference

That's all the formulas you need to know for additional!!!

Hope I helped! =D

You don't need to to know them, only use and manipulate them, and the units of course.

The formulas are provided for you on the first page of the exam paper :)

Just learn the one's that are not on there, but the possibility of any formula-needing question, which isn't relevant to those provided is HIGHLY UNLIKELY.
