One gesture · twelve worlds

Drop Lab

Same object. Same metres. Same seconds.
Local gravity in vacuum · Model / sources

Grab any object to move all twelve. Flick to toss, or hold still and let go to drop. Marks show every 0.25 s of flight.

Keyboard: arrows move; Shift + arrows aim a toss; Enter or Space launches. Escape clears the aim.

Model, assumptions & sources

Every cell uses the same length scale, clock and 1 kg point object. Gravity is constant at the dataset's effective surface or 1-bar reference level. There is no air, terrain, bounce or object size. Giant planets have an imaginary laboratory platform, not a solid surface.

Free fall is analytic: x = x₀ + vₓt and y = h + vᵧt − ½gt². Every copy receives the same release velocity. The first platform contact stops motion; the listed impact speed is immediately before contact. Equal-time trace marks continue in 0.25 s increments until impact.

One shared clock ends at the last impact, rounded up to the next hundredth of a second. Scrub to compare the same instant on every world. Shared links preserve the release position and velocity. Replay repeats the same launch; Reset gathers the objects at the release position with no velocity.

Launch speed is limited to 2.3 m/s, keeping upward tosses inside every frame. The same metre scale applies to all twelve worlds. The platform extends beyond the picture: a sideways toss may leave the frame, with an edge marker and true measurements tracking it. Trajectories are never bounced, wrapped or rescaled.
