No, the auxiliary verb "to be" is changed depending on the situation it is being used at the moment: In the present participle tense: - I am watching a movie. - He/she/it is watching a movie. - You/we/they are watching a movie. In the past participle tense: - I/he/she/it was watching a movie. - You/we/they were watching a movie.

No; there are very clear rules about using the different forms of "to be" and you should learn them properly first. Ivan has already given you the example sentences you need.
