Meritnation experts i do not have tenses in my study material i checked plz understand explain me

Dear Student,

"Present participle" form of the verb is used to define an active work. 
For example:
I am studying. 
The verb usually ends with "ing".

"Past Participle" form of the verb is used in the perfect tense and usually ends with "ed". 
For example:
I had stayed in the town. 

Regards
