Newton cradle: one incoming ball, one outgoing ball

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Show one raised end ball released toward a row of four touching suspended balls. After contact, the opposite end ball swings outward while the middle balls remain close to their original positions. End near that outgoing ball’s first turning point, before a return collision.

This original shot plan has not been tested. Use an aligned five-ball desktop cradle with intact suspension strings. Exclude a long oscillation loop, simultaneous release of several balls and numerical conservation claims.

2. Authorized first frame

Prepare your own or authorized photograph or accurate drawing. The leftmost ball is held a small distance leftward by one hand; the remaining four touch along a horizontal rest line. Show the frame, suspension attachments and each ball silhouette.

Use a near-side view with a slight angle that separates the strings without hiding the contact row. Leave space on both ends for small swings. Use a frame corner as a fixed reference; avoid reflections resembling extra balls.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Start from my authorized image of a five-ball Newton cradle with the left end ball held slightly outward and the other four balls touching in a level row. Keep the camera, lighting, frame and upper suspension attachments fixed. The original hand releases the left ball and withdraws. Let that same ball swing inward on its original strings and reach the adjacent ball before the right end ball begins its main outward swing. Preserve five separate ball identities and their original string connections. After the contact, show the rightmost ball leaving the row along its own suspended arc while the three middle balls stay close to their resting positions. The incoming ball remains near the row after the transfer. Do not turn this into five balls traveling together or a sequence of falling tiles. End near the right ball’s first outer turning point; allow natural deceleration without holding it unnaturally aloft. No return impact, second release, broken string, extra ball, cut, camera motion or numerical overlay.

1. Establish, first fifth: identify the held left ball, four touching balls and all suspension connections.
2. Release and transfer, middle three fifths: inspect inward approach, first contact and right-end departure in that order.
3. End, final fifth: follow the outgoing ball as it slows near its first outer turning point, then end the clip.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

• The left ball is visibly released and follows its original suspended arc toward the row.
• The main rightward departure follows the incoming contact instead of preceding it.
• Five ball silhouettes and their string attachments persist without swaps or duplication.
• The three middle balls remain near the rest row while the right end ball separates.
• The outgoing ball slows near its turning point without a prolonged unsupported freeze.
• If the incoming contact is skipped or hidden, record transfer timing as inconclusive; endpoint motion alone cannot prove contact.

6. Fix one failure

• All balls swing together: assign the outgoing motion to the far end and retain the middle row near rest.
• The far ball moves early: separate approach, contact and departure into explicit shot beats.
• Strings detach or stretch: reduce swing size and keep the full suspension visible.
• A ball remains frozen at its peak: end the clip at the turning point instead of requesting a long hold.
• Reflections resemble extra balls: simplify the authorized background and reduce surrounding shiny objects.

7. Ending and limits

End with the right ball near its first turning point and the remaining four near the original row, all still suspended.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 result, impact measurement, energy balance or ideal elastic-collision proof is supplied. Tiny middle-ball motion and unresolved contact intervals cannot be quantified from this brief.

The domino task propagates falls through changing support contacts. This shot keeps a suspended middle row near rest and transfers visible departure to its far end. The pendant task has no intervening contact row.
