Gaon ke mele mein Anjali seedhi patri par khilauna train, ghoomta giant wheel, aur aage-peeche jaata bada jhoola dekhti hai. Har ek alag tarah chalta hai!
Linear gati: seedhi line mein chalna: seedhi patri par train, girta seb, sapaat farsh par gend. Circular gati: kisi kendra ke chaaron or gol chalna: merry-go-round, pankhe ki pankhudi ka sira, dhaage par ghumaaya patthar.
Oscillatory gati: kisi nishchit bindu ke aage-peeche chalna: jhoola, pendulum, chheda gaya guitar ka taar, see-saw. Barabar samay ke baad dohraane wali gati, jaise pendulum ya pankha, periodic kehlati hai.
Kuch cheezein ek saath ek se zyada gati dikhaati hain: cycle seedhi aage chalti hai (linear) jabki uske pahiye ghoomte hain (circular).
Explore: gatiyaan sort karo.
- Linear, circular ya oscillatory?
Yaad rakho
- Linear: seedhi line. Circular: kendra ke chaaron or. Oscillatory: aage-peeche.
- Barabar samay mein dohraane wali gati periodic hai; kuch cheezein ek se zyada gati dikhaati hain.
