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
