Falling is Normal

I move from basic math concepts which I "know" by instinct to other things that are harder to prove, but still just as much of my knowledge base.

Let's move to "gravity."  I won't get into the math behind it, for that is in the territory into which geniuses dare to tread!  But I will speak to the concept.

I know that things FALL.  How much more basic can you get?  If there is any space at all between my hand and the floor, when I let go of an object, it falls to the floor. I've heard, and I've seen video evidence to prove it, that all objects fall at the same speed in a vacuum.  That is convenient for making calculations if one knows the math.

Related to gravity is "weight."  This is the evidence of what in science is called "mass" and "density."  The fact that a feather takes longer to fall to the ground that a marble is because the air around us has both mass and density.  Because of this, we have weather as the air is heated to change its density.

Personally, I experience gravity's effect in whatever I am doing.  As I sit here typing this blog, I can feel my body pressing against the chair.  If I am not careful, my legs will grow numb based on pressure distributed upon my hips.  The keyboard rests securely upon the flat surface of the desk, making typing possible.  All thanks to gravity.

If I were to go outside to play a game of catch with my grandson, gravity would be there to challenge me.  I would take advantage of the fact that the ball is of such a mass and density as to be able to temporarily "defy" gravity due to the energy imparted to it by my releasing it in a forward motion.  That motion, though, would diminish with distance as gravity worked by the laws of motion. The ball would either end up on the ground or in the hands of my grandson.

In all likelihood, my grandson's return of the ball would take a curved line.  This line would put the ball further from the ground for a moment.  The arc it forms obeys the laws of gravity and I have to adjust to intercept the ball.

So, What do I know?

Things fall until they hit a surface.

Things have mass and density.

Things can "fly" when energy is exerted against them that is greater than the gravity that makes them fall.
