Polar - has a positive or negative charge, usually at the ends of the molecule.
Non polar - has no charge
Some molecules are polar because the charges of the element ions do not balance because the electrons are not shared equally. One atom might exert more force than the other, "hogging" the shared electron more. Look at a water molecule as an example of that.
Non-polar molecules share electrons equally in bonding leaving behind no charge. CO2 (and most carbon compounds) and all diatomic (O2, N2, etc) compounds are non-polar.
If this is for an assignment a) you'd better paraphrase and b) you'd better site a more credible source than Y! answers.
