Verb is one of the most important parts of a sentence. It conveys the action part of a sentence – come, go, sit, stand, dance, write, read, run, climb etc. Tense is the form with which the verb must be presented in a sentence.
Examples:
I go home.
I’m going home.
I have gone home.
I have been going home.
I went home.
I was going home.
I had gone home.
I had been going home.
I will go home.
I will be going.
I will have gone home.
I will have been going home.
Notice here that the word “go” is being used in 12 different forms in order to convey 12 different meanings. All of these 12 forms emerge from the three basic tenses of the verb “go”:
Go (present tense), went (past tense), and gone (past participle) or,
Go (simple tense), went (past tense), and will go (future tense)
Let’s take another set of examples and identify the 12 verb tenses accordingly:
She breaks her hand –Simple Present Tense
She is breaking her hand — Present Continuous Tense (suggests an ongoing action in the present tense)
She has broken her hand — Present Perfect Tense (suggests a completed action in the present tense)

Unless it is a grammar school, not many English speaking people bother about identification of tenses. Their usage comes naturally with the fluency of the language.
