Hello,
.
Pehle ham circular aur  motion me baareme samjhinge baad me aapku automatically samaj me aajata.
.
Circular matlab chaaro taraf borders rehna.
example=circle/ring shapes/ aur koi bhi cheez circular me aati ho.
.
Motion matlab move hote rehna.
Example= aap Ab Kutch kaam se bahar nikle,aap Jab tak chalte rehta ya bike pe jaate rehte aap motion me rehte.
.
Cleared till here.
.
Abb circular motion Ka matlab hai ki eak move hote rehna.
Circular motion me eak cheez ya Insaan Ka direction lagataar change hote rehta.
Example= aap square ground me bhaag re, aap apna direction 4 times change karte kyuki ground Square hai aur share Ku 4 sides rehte.
Agar aap circle ground me bhaag re toh every second Aapka direction change hote rehta, kyuki circle has no perfect border.
.
Circular motion will be measured by speed=distance/time
.
Circular motion me jab ham rehta apna speed, direction aur time wo sab cheez consider karte.
.
Circular motion me 2 types hote hai.
Accelerated circular motion

• agar apna speed badte raha jab ham Kutch activity perform karre it is called accelerated motion

.
Uniform circular motion

• Apna speed constant rehna matlab Nahi badna Nahi Kam hona. Agar ham Kutch activity eak he speed me karre then it is said to be a uniform motion

.
I hope aap samaj gaye.
Thank you
