IGCSE PHYSICS Topics : Formulae and Laws

Forces and Motion

Hooke's Law:

You may also have to add atmospheric pressure to get the total pressure.

Energy and Power

Electric Circuits

for resistors in series

Charge= Voltage*Capacitance

Kirchoff's Laws

2^nd Law - The voltages sum around a circuit loop add to the supply voltage

1^st Law: Current into a node equals current out.










Latent Heat
Energy to evaporate m kg of liquid=ml, l=Specific Latent Heat of Vapourization
Energy to melt m kg of liquid=ml, l=Specific Latent Heat of Fusion
Energy to heat m kg of a substance by T degrees =mcT, c=Specific Heat Capacity
