Street Physics

About Street Physics

Street Physics is an open-ended browser playground where objects follow simple physical rules. Place shapes in the arena, change materials, add a burst of energy, or let gravity take control. There is no prescribed route: each session begins with a blank space and a question of your own.

What is Street Physics?

This edition turns the idea of a physics sandbox into a fast, accessible web experiment. You can play Street Physics online without an installer, account, or progress system. Instead of chasing a score, you build small scenarios and observe how they develop. Objects collide, bounce, stack, and respond to impulses, making even a simple arrangement feel different every time.

Gameplay overview

Physics system

Gravity pulls every loose object toward the floor while collision response keeps shapes moving, bouncing, and settling naturally.

Objects and tools

Switch between balls, boxes, heavy objects, and explosive impulses. Each tool changes the scene in a visible way.

Creative freedom

There are no fixed levels. Make a tower, build an obstacle course, or fill the entire arena and see what survives.

Controls

• Mouse: choose a tool, then click or drag in the arena to place and move objects.
• Keyboard: use 1–4 to switch tools, Space for an impulse, and R to reset.
• Touch: select a toolbar item and tap anywhere in the arena.

Tips for playing Street Physics

• Start with only a few objects so you can understand each reaction.
• Place heavy blocks above lighter balls to create quick chain reactions.
• Use impulse mode near a crowded area for the most dramatic result.
• Build close to the floor when you want stable structures.
• Reset often—each new arrangement is a different experiment.
