osi lwen ke w ap konsène ke tan karke la pa te nesesèman k ap deplase nan tout tan sa a lè ou pa te kapab wè background nan Lè sa a, mwen kwè petèt li te pi difisil pou ou pou w reyalize ke ou te nan k ap deplase ankadreman nan referans bagay enpòtan nan reyalize isit la tout ankadreman nan referans k ap deplase nan vitès konstan ak respè youn ak lòt yo se ekivalan doktè Ivy te montre nou, men mouvman an nan boul la ki te lage nan la k ap deplase kart te sanble ak nan ankadreman aktyèl la nan referans ak nan ankadreman an machin mosyon an sanble pi senp nan yon machin kounye a mwen ta renmen ou gade mosyon an blan tach ta pwobabman revèy la k ap deplase soti sèk

as far as you're concerned that time the karke wasn't necessarily moving at all that time when you couldn't see the background then i think perhaps it was harder for you to realize that you were in moving frame of reference important thing to realize here all frames of reference moving at constant velocity with respect to one another are equivalent doctor ivy showed you but the motion of the ball that was released from the moving karte looked like in the current frame of reference and in the car frame the motion looks simpler from a car now i want you to watch the motion white spot would probably be the clock moving out circle
