Video narration
Agar tum ghar se nikal kar ghumavdar raaston se chalo aur phir wahin laut aao, to kya distance aur jagah ka badlav ek hi honge? Raaste ke har mod se guzre, isliye poore raaste ki lambai jodoge. Yahi distance hai: chalne mein tay hua poora raasta. Raasta kitna bhi ghumavdar ho, har hissa ismein gina jaata hai. Ab shuruaat aur ant ki jagah ki tulna karo. Displacement yani shuru se ant tak tumhari jagah mein hua badlav; badlav ki disha bhi mayne rakhti hai. Ise har mod se nahi, sirf shuruaat aur ant se samjho. Yahi fark hai: tumne lamba raasta tay kiya, lekin pahunche wahin jahan se chale the. Raasta aur jagah ka badlav, do alag maap hain. To jawab? Distance poora chala hua raasta hai; displacement shoonya, kyunki tum wapas wahin aa gaye. Agla bhaag kis vishay par chahiye? Comment mein batao.
