Mass-Spring System - Interactive Simulation
Explore simple harmonic motion with a mass-spring oscillator. Visualize how period depends on mass and spring constant (not amplitude), observe energy transformations between potential and kinetic, and understand phase relationships between position, velocity, and acceleration.

Simple Pendulum
Explore the physics of simple harmonic motion with an interactive pendulum simulation. Adjust length, mass, gravity (including planet presets), damping, and initial angle. Watch real-time energy transformations and measure the period.

Projectile Motion
Launch projectiles at different angles and velocities. Explore how gravity and launch parameters affect trajectory, range, and height. Compare with and without air resistance, and test on different planets.

Electric Field Visualization
Visualize electric field lines, vectors, and equipotential surfaces around point charges. Add, drag, and remove charges to explore how fields interact. Launch test charges to see their motion through the field.
