It is officially called -- Are you ready this super technical term? -- the "upside-down question mark." It is placed at the beginning of any Spanish sentence that is a question.\n\nI actually feel that the English language should adapt this.  Have you ever started reading out loud and when you find yourself getting to the end of a sentence, you see the question mark and realized that you didn't phrase it like a sentence?  Having the question mark at the beginning of the sentence, lets you know in advance you are reading a question :)

I think it is spelled "oopsidaisy", and it usually is used when you drop something unintentionally, and want to indicate to others that you are making fun of yourself lightly, as you stoop to pick it up.  \nThough "upsidaisy" might be said when you are picking up a small child, just as a nonsensical statement to indicate "hey, I'm picking you up.  let's smile and be good!"  :)\nI've heard both of these uses.

1 It is an adjective. Something or someone is down-to-earth (or 'down to earth') is concerned with doing practical things and solving problems in a practical way, rather than with abstract theories. Example - They have much more down-to-earth reasons to disbelieve him. She's a down-to-earth sort of woman with no pretensions.\n\n2 'Driven' is simply the past participle of the verb '(to) drive'. Example - A man driven by greed and envy loses his power of justice. The car was driven by a liveried chauffeur.

I thought it meant how severe something was but I am not finding anything to back me up on that. I think, from looking on the internet, people use it for the word gravity. No other definition for any such word - just suggestions to the other forms that relate to gravity.

The instant an object is released as it is thrown upwards, it begins to accelerate downward.  This downward acceleration is caused by gravity (the force of weight, m*g, acting downward on the object).  Although the object may continue to travel upwards for a brief time, it is continually slowing in the upward direction as it accelerates towards the ground.\n\nObjects "fall" towards the ground (in the direction of the center of the Earth's mass) since that is the direction of the force of gravity is exerted on them.  An object cannot "fall" up since there is no net force acting in that direction.

up, down, and upside down are relative.  You consider up to be away from the pull of gravity (away from the center of the earth), and down to be the opposite.  No, they are not "upside down", but their head is pointed in the opposite direction of yours (assuming you are standing normally, they are too, and you are on opposite sides of the world).
