Powder Game vs Gravity Physics

Imagine the cool phenomenon when the wind blows the falling leaves. This game physics simulates the phenomenon with powder (dots)! You can choose more than 30 different variations of the dot. Water, fire, oil, gunpowder, metal, seed, birds, Ant and more. The various reactions when in hit with a dot and a dot. The explosion on hit with fire and gunpowder. Trees grow when in hit with the seed and sand.

Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES • Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth • True N-body gravity — every body pulls on every other body and on your ship, in real time • Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn • Time controls — speed up months of orbital motion or slow down to precision-dock in real time • Trajectory prediction — see where your current heading will take you before you commit • Flight trail — trace your path across millions of kilometers • Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.
