Physics
Physics tools for middle school through AP and IB
Every constant comes from NIST CODATA 2018 (retrieved 2026-10-05), stored with provenance and never taken from AI memory. Every answer is computed by two independent methods and checked for physical consistency. No AI is used, so these tools never use a generation credit and answers are independently checked.
Motion Problems
Kinematics, free fall, and projectiles with full work shown
Problem sets with diagrams, answer keys showing every step, and a conventions box. Every answer computed by two independent methods (closed form + numerical simulation).
Open toolForces and Newton's Laws
Free-body diagrams, friction, inclines, and connected objects
Problem sets with free-body diagrams drawn from solved force vectors. Every problem solved with two axis choices and checked for Newton's third law consistency.
Open toolCircuits
Series, parallel, and combination DC circuits with schematics
Circuit problems with schematics drawn from the netlist, V-I-R tables, and answer keys with reduction steps. Verified by KCL, KVL, and power balance.
Open toolEnergy and Momentum
Work, energy conservation, impulse, and collisions
Problem sets with energy bar charts, collision diagrams, and full work. Every answer computed by two independent methods (energy + kinematics, momentum + CM frame).
Open toolWaves and Optics
Wave properties, sound, light, refraction, and lenses
Wave graphs, standing waves, ray diagrams, and lens/mirror problems. Every answer computed by two independent methods (scalar + vector Snell, lens equation + ray tracing).
Open toolElectric Fields
Coulomb's law, field maps, potential, and capacitors
Charge configurations, field vectors, parallel plates, and capacitors. Every answer computed by two independent methods (analytic + numerical potential gradient).
Open toolPhysics Reference Sheet
Constants, formulas, and conventions from verified sources
A printable reference sheet with SI units, constants from NIST CODATA 2018, kinematics and force formulas, and circuit equations. Student and fill-in versions.

How these tools were checked
- • Constants: NIST CODATA 2018 (physics.nist.gov/cuu/Constants), retrieved 2026-10-05.
- • Every answer computed by two independent methods (closed form + numerical simulation, or two axis choices, or reduction + nodal analysis).
- • Physical consistency checks: Newton's second law per body, KCL, KVL, and power balance for circuits.
- • No AI used in generation or checking — these tools never use a generation credit.
- • Diagrams generated from the solved data and verified against it.
