Aree, displacement nikaalna hai toh area le lo graph ka! Line time axis ke neeche bhi jaaye, phir bhi area hi batayega total displacement. Bas, neeche ka area negative mein ginna — matlab object pichhe gaya kuch der.
Yeh velocity-time graph ki line meri night shift ki bus jaise hai — kabhi upar chadhti hai, kabhi neeche utarti hai pahadon mein. Par akhir mein jo total area aaya, wohi batata hai ki main ghar se kitna door nikla... aur kitna lautke aa paaya.
