Do you know which exam e.g.

Do you know which exam e.g. AQA, OCR, Edexcel?

List of useful equations for Physics

In GCSE Examinations,

we don't usually get any equations I don't think, but here is a list that will help you...

Density, mass, volume:     d = m/v

Speed:     s = d/t

Acceleration:     change in velocity / time taken

Force, mass, acceleration:     f = m x a

Momentum:     mass x velocity

Weight:     mass x g

Moment of a force:     moment of a force about a fixed point = force x perpendicular distance from point

Stretched spring:     load = spring constant x extension

Pressure and force:     pressure = force / area

Pressure in a liquid:     pressure = density x g x depth

Temperature:     Kelvin temperature = temperature in ^oC + 273
 
Compressing gases:     pressure1 x volume1 = pressure2 x volume2
 
Work:     work done = force x distance moved in direction of force
 
Gravitational potential energy:     mass x g x height
 
Kinetic energy:     1/2 x mass x velocity^2
 
Energy and temperature change:     energy transferred = mass x specific heat capacity x temperature change
 
Energy and state change:     energy transferred = mass x specific latent heat
 
Power:     work done / time taken = energy transformed / time taken
 
Efficiency:     work done / total energy input = energy output / total energy input = power output / total power input
 
Waves:     speed = frequency x wavelength
 
Refraction of light:     refractive index = sine of angle of incidence / sine of angle of refraction
 
Total internal reflection:     sine of critical angle = 1 / refractive index
 
Charge and current:     charge = current x time
 
Resistance, PD (voltage), current:     resistance = PD / current
 
Resistors in series:    R = R1 + R2
 
Resistors in parallel:     1/R = 1 / R1  +  1 / R2
 
Electrical power:     power = PD X current
 
Electrical energy:     energy transformed = power x time
                                                                         = PD x current x time
 
Transformers:     output voltage / input voltage = output turns / input turns
 
For 100% efficient transformer:     power input = power output
