Projectile motion is a part in our life actually. Knowing just formulas cannot help you much. Following website describe this motion very well. I hope they can help you.

Seems that u want to know everything related to projectiles.At your high school level, it is sufficient to know just the outer content of the topic like formulae, definitions,few little ideas because, you have to study other things too.Ok, still if you want to know deep into it, you can do do it your own.Get physics text related to higher classes 11/12, magazines from library or elsewere.The key thing is text book.From the net, you can get wide varied information, but those knowledge can give you huge test for your understanding capabilities…at last i would advice you to get just your enough knowledge in general, try by-hearting what u have in your current text,get the basic thing first.
