Generally, “….’s..” can be used with the singular noun. It means possession. For example;
John’s mother=mother of John
Dog’s tail = tail of dog
Generally, “….’….”(not …s’…) can be used with the plural noun containing “s” suffix. For example;
Boys’ school = school of boys
Girls’ school = school of girls
As a contraction, “…’s…” can be used instead of “has” “was” and “is”. For example;
She’s a teacher. (= She is a teacher.)
She’s a car. (=She has a car.)
She’s there yesterday. (=She was there yesterday.)
Hope that help you.

thanks a million for the explanation :)

it makes sence :)

i have another question...

based on the example about...

i know that..

mary's car.... is right...
car's door is wrong.. because someone told me so.... (during my school days)
i think it should be car door

now, is there any explanation why i can't put 's on some nouns or whatever it is? ... so that i can use it correctly...

thanks for your patience...

Generally, "...'s..." can be used with living things. For example;
Mary's house
dog's tail
cat's hair
"...of...." can be used with non-living things. For example;
the entrance of the house (not house's entrance)
the door of the car (not car's door)
