Complete list of all GCSE Physics Equations

Below is a complete list of all of the GCSE Physics Equations that you could need during your exams.

GCSE Physics Equations by Exam Board

This includes all major exam boards – AQA, Edexcel and OCR. There are some minor differences between exam boards and so you can access complete equation lists for each at the below links. 

efficiency = useful power output/total power input
period = 1/frequency
magnification = image height/object height
wave speed = frequency × wavelength
energy transferred = power × time
efficiency = useful energy transferred/total energy transferred
charge = current × time
potential difference = current × resistance
potential difference = work done (energy transferred)/charge
power = energy/time
energy transferred (work done) = charge flow × potential difference
power = potential difference × current
power = (current)2 × resistance
HT force = magnetic flux density × current × length of conductor
potential difference across primary coil × current in primary coil = potential difference across secondary coil × current in secondary coil
HT potential difference across primary coil/potential difference across secondary coil = number of turns in a primary coil/number of turns in secondary coil
weight = mass × gravitational field strength
average speed = distance/time
acceleration = change in speed/time taken
(final speed)2 – (initial speed)2 = 2 × acceleration × distance
HT momentum = mass × velocity
HT change in momentum = resultant force × time for which it acts
moment of a force = force × distance (normal to direction of the force)
force = mass × acceleration
work done = force × distance (along the line of action of the force)
kinetic energy = 0.5 × mass × (speed)2
gravitational potential energy = mass × gravitational field strength × height
power = energy transferred/time
density = mass/volume
change in internal energy = mass × specific heat capacity × change in temperature
energy to cause a change of state = mass × specific latent heat
force exerted by a spring = extension × spring constant
energy stored in a stretched spring = 1/2 × spring constant × (extension)2
pressure = force normal to a surface/area of that surface
for gases: pressure × volume = constant
(for a given mass of gas and at a constant temperature)
HT pressure due to a column of liquid = height of column × density of liquid × gravitational field strength
energy transferred = current × voltage × time
refractive index = sin(angle of incidence) / sin(angle of refraction)
sin(critical angle) = 1/refractive index
efficiency = useful energy output/total energy output x 100%
pressure/temperature = constant
Orbital speed = 2 x π x orbital radius/time period
Change in wavelength/reference wavelength = velocity of a galaxy /speed of light
