Physion is a free browser-based 2D physics simulator. Draw rigid bodies (circles, rectangles, capsules, polygons, gears, text and polylines), connect them with joints and springs, then simulate liquids, soft bodies and particle emitters. Boolean shape operations and a scriptable laser raycast are built in. Any object can carry a JavaScript node script, so scenes can react to collisions, measure themselves or drive their own motors.

Nothing to install: it runs in the browser, which is what makes it usable on locked-down school hardware and Chromebooks.

Free to use, with optional paid plans.

You can create different types of bodies inside its physics world with different parameters like restitution, friction, velocity etc. attach them with different types of Joints like spring, rope, chain, pulley etc. Due to its native Physics engine the accuracy in solving is great.

One can visualize the motion with the numerous built in tools like tracers of points on body or Body ghosting, Graphs between different parameters( like KE, speed, velocity, momentum, etc), FBD of grouped and ungrouped objects, Camera tool ( to set frame of reference) etc.

It supports gravitational , electric, magnetic and buoyancy fields. One can even set variable fields ( time dependent ) and can easily change the fields as well using sliders.

One can create their own GUI elements in it like buttons , sliders , checkboxes , List , dialog etc. and even can write scriptable codes in them for different events in its in-built powerful scripting editing tool.

  • Time flies, because we're spending almost a quarter of each day scrolling
    'time scrolling by' with alias of clock time displayed everytime 'enter'/'return' pressed[0a][0b] would seem a bit easier to do than pop-up physics demo with 'clock displaying time flying through demo virtual space[1].
