Physics Δ — Online Physics Calculators Suite
Physics Δ is a collection of focused physics calculators for school and university level problems. Each tool is built around clear formulas, simple inputs and instant results in SI units — following the DELTOOLLAB philosophy: simple tools, clear logic.
What Physics Δ Includes
The Physics Δ suite covers seven core areas of classical and modern physics. Every calculator works as a compact “lab” for its topic, with readable formulas and minimal interface — no registration, no distractions.
- Mechanics Δ — speed, acceleration, force, work, kinetic and potential energy, power and pressure (school-level mechanics and basic dynamics).
- Electricity Δ — Ohm’s law, voltage, current, resistance, electric power, charge and energy in simple DC circuits.
- Optics Δ — thin lens equations, magnification, refractive index, Snell’s law, optical power and critical angle with unit switching.
- Thermodynamics Δ — heat for heating and cooling, specific heat, temperature change and heat of phase transitions (fusion and vaporization).
- Waves Δ — wave speed, wavelength, frequency and period for basic wave and sound tasks, with flexible units for λ and f.
- Gravitation Δ — Newtonian gravity: force between masses, surface gravity, weight near a planet, orbital speed and escape velocity.
- Nuclear Δ — radioactive decay, half-life, decay constant and activity based on exponential decay laws.
How Physics Δ Works
Each calculator is focused on a single branch of physics and uses:
- clear input fields with unit hints and simple validation;
- instant results with the formula shown in the final expression;
- support for common unit switches (meters / centimeters, Hz / kHz, J / kJ, kg / g);
- school and introductory university level physics notation.
Physics Δ is designed as a neutral, ad-light environment for students, teachers, self-learners and engineers who need quick, reliable physics calculations without heavy interfaces or account creation.
DELTOOLLAB — tools for logic, science and clear thinking. Physics Δ is the science layer of the platform, dedicated to clean and accessible calculations.
