D Delta Physics Engine

See Physics Happen

Interactive simulations bring kinematics, forces, energy, waves, and electromagnetism to life with real-time data visualization.

Launch Simulator

Mechanics & Motion

Study kinematics, Newton's laws, work-energy theorem, momentum, rotational dynamics, and gravitation with adjustable-parameter simulations.

Waves & Optics

Explore wave properties, sound, interference, diffraction, reflection, refraction, lenses, and the electromagnetic spectrum through virtual experiments.

Electricity & Magnetism

Build circuits, measure fields, analyze Coulomb's law, Gauss's law, Faraday's law, and electromagnetic induction with hands-on tools.

What We Offer

🚀

Motion Lab

Launch projectiles, adjust gravity, friction, and air resistance to observe kinematic equations in action.

âš¡

Circuit Builder

Wire resistors, capacitors, and inductors in series and parallel — measure voltage, current, and power.

🌊

Wave Tank

Generate waves, observe interference patterns, standing waves, and Doppler effect in real time.

📈

Data Analysis

Collect simulation data, create graphs, perform linear regression, and calculate uncertainties.

What Learners Say

Being able to change variables and instantly see the effect on motion made physics intuitive.
