About this tool
Gravity Well is a free online visual effect. Canvas 2D particles orbiting a central gravity point, like a planetary system. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, a gravitational field scene will be displayed. There is a massive celestial body in the center of the screen, and the surrounding particles will move in an elliptical orbit or spiral fall under the action of gravity. Parameters such as the gravitational constant, the number of particles, and the initial velocity can be adjusted.
The whole process is purely front-end animation, calculating the gravity exerted on each particle based on Canvas 'universal gravitation formula, and then updating the position and velocity. Support mouse clicks to add new gravitational sources.
It is suitable for use as astronomy science popularization, physics teaching demonstrations, or purely appreciating the dynamic beauty of particle motion in the gravitational field. The realization principle is Newton's law of universal gravitation and numerical integration.
Gravitational well is a visual effect that simulates the gravitational field of celestial bodies. Based on Canvas, it renders the motion trajectory of particles in the gravitational field in real time.
