u need the difference??
Verbs which have the past or the present form are called FINITE verbs. Verbs in any other form (infinitive, -ing, or -ed) are called NONFINITE verbs. This means that verbs with tense are finite, and verbs without tense are nonfinite. The distinction between finite and nonfinite verbs is a very important one in grammar, since it affects how verbs behave in sentences.

Finite verbs (main verb) stand after subject and must be conjugated to the subject in simple present tense.
                         For example: I go fishing. She goes fishing. In this case, "go" the finite verb and must be conjugated follow the subject. 

Infinite verbs, in summary, are: can, could,may,might, do*, did*, ...(*:these verb can be finite or infinite). For example: 
                                 I can eat a whole chicken. (There are 2 verbs in this sentence. "Can" is the infinite verb and "eat" is the finite one). 
May I open the window? ( "May": infinite, "open": finite)

Well thats FINITE and not INFINITE........

Verbs which have a tense i.e. are in past or present tense. n also have a subject. They can change in some situations like tense, etc.
like - she is dancing to the tune.
Here 'she' is the subject and 'dancing' is present tense. The word 'dancing' can change if we change the tense, like - She danced to the tune.

Verbs that are not showing tense. These are usually to-verbs and ing- form of the verbs. In this the verb is not actaully acting as a 'verb' but as a 'noun'. They do not require a subject. They do not change in  any situation.
like - she likes dancing.
Here 'dancing' is acting as a noun and not a verb. 'dancing' will not change here. Like- She liked dancing.
another eg. (that does not require a subject)- Leaving home at night can be dangerous.
