AQA GCSE Physics (8463) Equations Flashcards

Vocabulary and formula-based flashcards derived from the AQA GCSE Physics (8463) Equations Sheet, including both Foundation and Higher Tier equations.

Pressure due to a column of liquid

$p = h \rho g$ where pressure $(p)$ is equal to height of column $(h) \times$ density of liquid $(\rho) \times$ gravitational field strength $(g)$

Kinematics equation for velocity and distance

$v^2 - u^2 = 2as$ where $(final\text{ }velocity)^2 - (initial\text{ }velocity)^2 = 2 \times acceleration \times distance$

Force (in terms of momentum)

$F = \frac{m\text{ }\times\text{ }\triangle v}{\triangle t}$ where $force = \frac{change\text{ }in\text{ }momentum}{time\text{ }taken}$

Elastic potential energy

$E_e = 0.5 \times k \times e^2$ where energy is $0.5 \times spring\text{ }constant \times (extension)^2$

Change in thermal energy

$\triangle E = mc \triangle \theta$ where change in energy is $mass \times specific\text{ }heat\text{ }capacity \times temperature\text{ }change$

Period

$T = \frac{1}{f}$ where $period = \frac{1}{frequency}$

Magnification

$$magnification = \frac{image\text{ }height}{object\text{ }height}$$

Force on a conductor

$F = B I L$ where force is $magnetic\text{ }flux\text{ }density \times current \times length$ (at right angles to a magnetic field carrying a current)

Thermal energy for a change of state

$E = mL$ where energy is $mass \times specific\text{ }latent\text{ }heat$

Potential difference and turns ratio (Transformers)

$\frac{V_p}{V_s} = \frac{n_p}{n_s}$ where the ratio of potential difference across primary to secondary coils equals the ratio of the number of turns in primary to secondary coils

Transformer power equation

$V_p I_p = V_s I_s$ where potential difference across primary coil $\times$ current in primary coil is equal to the potential difference across secondary coil $\times$ current in secondary coil

Gas Law (Boyle's Law)

$pV = \text{constant}$ where $pressure \times volume = \text{constant}$ for gases
