🔋 Simple Circuit Simulator
💡 When the switch is closed, current flows from the battery through the wires to the bulb, making it glow! Try changing the voltage to see the bulb get brighter or dimmer.
🪐 Pendulum Simulator
🪐 A pendulum swings because gravity pulls the bob back toward the center. The period depends on length and gravity — not on the starting angle (for small angles)!
