Sthiti Batana

Class 6 Science · Chapter 5: Lambai ka Maap aur Gati · NCERT Curiosity section 5.5

Seekho

Ek mehmaan Ira se poochhta hai, "Library kahan hai?" Wo kehti hai, "School gate se 50 m poorv mein." Kuch kahan hai ye batane ke liye chahiye ek reference point (gate), doori (50 m) aur disha (poorv).

Kabir chalti bus mein baitha hai. Kya wo chal raha hai? Apni seat ke mukaable wo sthir hai. Bahar ke ped ke mukaable wo chal raha hai! Koi cheez sthir hai ya gati mein, ye chune gaye reference point par nirbhar hai.

Koi cheez gati mein hai agar reference point ke mukaable samay ke saath uski jagah badle. Agar jagah na badle to wo sthir hai.

motion = change of position with time

Yaad rakho

  • Sthiti reference point, doori aur disha se batate hain.
  • Gati samay ke saath jagah badalna hai; sthir ya gati reference point par nirbhar hai.

Haan. Dharti ghoom rahi hai aur Suraj ke chakkar laga rahi hai, isliye Suraj (ya Chaand) ke mukaable tum bahut tez chal rahe ho, baithe hue bhi.
