will vs would

<p>can someone give me some clear examples to clarify these two for me?
i seem to ge confuse by these two all the time; i can't really differentiate the 2.</p>

<p>thanks~</p>

<p>I will go to the mall tomorrow. (Definite)</p>

<p>I would go with you if I could, but I can't, so I won't. (Indefinite)</p>

<p>To give another example of the shades of meaning:
"Do you think Obama will choose Clinton as his running mate?"
Asks you to predict a future event.
"Do you think Obama would choose Clinton as his running mate"
Asks you to evaluate Obama's considerations in making this decision.</p>
