Action verbs used with form of Be+ ING

what is the difference beetwen these two words HELP and HELPING.i mean when we add 'ing' with word does it change its meaning.

= ACTION verb

Can I "help" you? (Simple Present tense.)

Sorry, but I can't help you now. (Simple Present tense.)

I am helping pratab. (Present Continuous tense.) Also called "Progressive" tense.

I (form of BE) am HELP (action verb) + ing (noun Pratab).

ACTION VERB = Subject + form of BE + ing + Object.

Remember this is only for action verbs. They are used in present continuous tense, so you use a form of BE + verb + ing.
