Science
Every physics and chemistry tool on Brainlag in one place: calculators, the periodic table and simulations you can run and measure, from GCSE to university.
Physics
GCSE
Give any three of s, u, v, a, t. Get the rest.
Ohm's Law and CircuitsV = IR, power, series and parallel resistors.
Physics FormulasDensity, pressure, energy and power, rearranged.
Half-lifeRadioactive decay: amount left, time, half-life.
Forces & accelerationPush harder than friction
Forces on a slopeWill it slide, or stay put?
Momentum and collisionsBounce, crunch or stick together?
Mass on a springStretch it, let go, watch it bounce
Waves on a stringAdd two waves, find the nodes
Refraction and Snell's lawBend light, then trap it
Lenses and ray diagramsWhere does the image land?
Series & parallel circuitsSeries or parallel: which wins?
Radioactive decayWhich nucleus goes next?
A-Level
