is moving on a trasition?

Nope. It's a verb form.

http://en.wikipedia.org/wiki/Transition_words

http://grammar.ccc.commnet.edu/grammar/transitions.htm

Both those sites have lists of transitional words and phrases.

thank you, but im writing an essay and im starting off a paragraph.

should i say:
Moreover, Barck Obama is going to fight global warming.

Yes, that is a good way to start a sentence in which you are going to add additional information to an already-started topic.

Good choice.

im not though(im not trying to sound rude if i do), and that's my problem i don't know what transition to use. can you help me?

You need to put this in context for me. Type in the paragraph before you plan to use the transition and one or two of the sentences after. Then I'll be able to help you more specifically.

Yes, moving on can be considered a transition in certain contexts. In general, a transition refers to a process or a period of change from one state, condition, or situation to another. When it comes to emotions or personal experiences, "moving on" typically refers to letting go of something or someone from the past and embracing a new phase of life. This could include getting over a breakup, healing from a loss, or accepting and adapting to a new situation. It involves a shift in mindset, emotions, and behaviors to adjust to the changes and move forward.
