Do capacitors have positive and negative terminals?

What are electrolytic capacitors? In what way they are different from normal capacitors? The charge on a capacitor depends on how i connect it to battery,but electrolytic capacitors have one long and short terminal to differentiate between positive and negative terminal. Why?

So read about it, and do your own research. You will learn more, and most importantly, you will learn how to learn more.

Some capacitors are polarised - They have a + and - terminal electrolytic are an example.
Correct, some are polarized, and some are not.

Try reading about it. We aren't here to do your homework for you.
Electrolytic capacitors are the best way to get a lot of capacitance in small space. They work by creating an anodic film on aluminium foil. Driven the right way, the anodic film doesn't break down.
