The equations are on your exam sheet. Marks are lost on picking the right one, rearranging it, converting units and showing working. Our solvers do all four, so you learn how.
Written and checked by a physics teacher. No sign-up, no app.
A 500 g ball moves at 36 km/h. Calculate its kinetic energy.
Each solver says which quantities you need and which tier it's on.
Solve for any letter. See the rearranged equation before the numbers go in.
Grams, km/h, kJ: converted to SI units and shown in the working.
Equation, substitution, answer and unit, line by line.
27 equation solvers planned across all eight AQA topics. New solvers are added every week.
Kinetic, potential and thermal energy, power and efficiency.
Charge, current, resistance, power and energy in circuits.
Density, specific latent heat and gas pressure.
Radioactive decay and half-life.
Weight, work, springs, moments, pressure, motion and momentum.
Wave speed, frequency, period and magnification.
Force on a conductor and transformers.
Orbits, life cycle of stars and red-shift (Physics only).
Explainers coming soon.
Project any solver in class to model a calculation, or link it from your department's revision page. Classroom mode and printable question sheets are coming soon.
