Physics a di roulette ball

Di ball

Long time dem did mek it outta ivory, den ivorine (a kind a celluloid), an now most time Teflon or a plastic like dat, 18 to 21 mm cross, a few gram. Casino keep nuff size an change dem, cause a smaller, lighter ballgearBallDi likkle ball weh di dealer fling roun di track di opposite way to di rotor. Modern ball mek outta ivorine or Teflon, 18–21 mm.Read di whole ting → bounce more pon di fretgearFretDi metal divider between two pocket pon di wheel (di likkle wall between pocket).Read di whole ting → an scatter wider, an dat good fi di house. Di ball cyaan magnetic, an dem check seh it round good; a ball weh nuh round drop early an wild.

Pon di track

Pon a roun track weh tilt, di ball need a centripetal force mv²/r fi keep turnin. Di track wall gi it dat force while di ball fast. As di ball slow dung, di force it need drop, till di part a gravity weh pull inward dung di tilt more dan wah di shape can hold, an di ball roll off. Di critical speed depend only pon di radius an di angle a di track, suh pon one wheel di drop speed nearly di same fram spin to spin, normally 1 to 1.3 m/s.

Ow it slow dung

Rollin friction tek weh energy at a rate weh roughly nuh change; air drag tek weh more wen di ball faster. Togedda dem mek evry lap a likkle longa dan di las one, by a amount yuh can predict. If yuh measure two or tree lap time one afta di odda, yuh can work out di friction an drag numba dem an figure out pon which lap di ball wi drop. Pon a clean wheel dat guess good to a few tenth a second; a dat timin predictor dem measure, an di deceleration page show di maths.

Di scatter

Afta it lef di track, di ball cross di aprongearApronDi slope part between di ball track an di pocket dem, weh di deflector dem deh.Read di whole ting → an most time it lick one a di eight deflectorgearDeflectorOne a di metal block dem pon di apron weh scatter di ball wen it a drop.

Nex name: slot, cup.Read di whole ting →” or one quarter a di wheel weh. Den it bounce cross di fret dem, sometime it jump back out a one pocket it did go inna already. Dem measure scatter fi evry wheel as a distribution a di final pocket compare to di pocket unda di drop point; pon modern wheel it normally cover 10 to 15 pocket pon each side, an some wheel show two or tree peak cause certain deflector get lick more often.

Wah dis mean fi di playa

Evryting up to di drop, yuh can know it inna theory, but it nuh useful inna practice widout equipment an late bet. Evryting afta di drop design so nobaddy cyaan know it. Suh di result dem a dis game random, nuh cause di physics random, but cause di information yuh need fi predict dem get mash up between di track an di pocket.
