Physik

Physik drops your layers into a 2D physics world where they fall, bounce, and collide, then bakes the result to TRANSLATION_XY keyframes, and, when they tumble, a ROTATION track too. You direct the simulation with gravity, materials, and forces; the tool runs it and turns the outcome into real timeline motion.

Select layers inside a frame. Each becomes a physics body using its real shape. Rects, ellipses, stars, polygons, vectors, and text all get matching collision meshes, so nothing collides as a crude bounding box.

Press Play to preview, Reset to return to the start, then Bake Keyframes to write the motion onto the timeline.

Every selected layer becomes one of three kinds of body.

Any body can also carry a function that adds force to the sim. Right-click a body in the preview for quick type and function access, or drag a spring noodle to connect two bodies.

The World tab sets gravity strength and direction, a bounding mode (walls or a bleed boundary), and air drag, the global rules the whole sim obeys.

The Types tab stores reusable material presets (Bouncy, Solid, Slippery, Attractor, Repulsor) that you can stamp onto a selection to set restitution, friction, and density in one click.

Tumble gives collisions real rotational response. Off-center hits and friction make bodies spin, and the bake adds a ROTATION track (the center-pivot compensation is handled automatically, since Figma rotates around a layer's top-left). Turn it off for the classic slide-only sim, and for sessions saved before Tumble existed.

Duration sets how long the simulation bakes; Fidelity controls how many keyframes are sampled per dynamic body. More fidelity tracks the motion more precisely at the cost of a denser timeline. Clear Keyframes removes the baked position and rotation tracks, and Save / Load persist your setup on the page.
