Interactive Physics Tools

Tools for Every Physics Topic

From kinematics and forces to waves and electricity. Each tool includes step-by-step worked solutions and visual diagrams.

Projectile Motion Calculator

Calculate trajectory, range, time of flight, and maximum height. Adjust launch velocity, angle, and height with an animated path visualization.

Circuit Calculator

Calculate voltage, current, resistance, and power using Ohm's law. Build series and parallel resistor networks with step-by-step equivalent resistance.

Forces & Free-Body Diagram Tool

Explore Newton's second law with interactive free-body diagrams on surfaces, inclines, and pulley systems.

Wave Explorer

Visualize transverse waves, superposition, interference, and standing waves with adjustable frequency and amplitude.

Energy Conservation Explorer

Track kinetic, potential, and spring energy as an object moves along ramps, roller coasters, and spring systems.

Kinematics Solver

Solve constant-acceleration problems with step-by-step solutions and motion graphs for all five kinematic variables.

Universal Gravitation Calculator

Calculate gravitational force, field strength, orbital velocity, and escape velocity with SVG force diagrams.

Electric Field Visualizer

Place point charges and visualize electric field lines and equipotential surfaces in a 2D interactive canvas.

Virtual Physics Labs

Structured Lab Investigations

Each lab includes guided experiment prompts, a data collection table with CSV export, and a lab report panel students can fill in and download as a PDF.

Pendulum Lab

Measure pendulum period at different lengths to derive gravitational acceleration. Plot T squared vs L and compare small and large angle behavior.

Hooke's Law Lab

Hang masses on a spring, measure extension, and find the spring constant from the slope of F vs x. Calculate elastic potential energy.

Momentum & Impulse Lab

Apply variable forces over time and see real-time force-time curves. Calculate impulse as area under the curve and compare to momentum change.

Gravity & Orbits Lab

Animate elliptical orbits, verify Kepler's Third Law, and measure orbital velocity with the vis-viva equation.

Circuit Builder Lab

Explore series, parallel, and combination circuits. Verify Ohm's law and Kirchhoff's laws with animated current flow.

Friction & Inclined Plane Lab

Find static and kinetic friction coefficients by adjusting the ramp angle. Watch real-time free-body diagrams and discover the critical sliding angle.
