Hey "bud"

If the earth is flat, when I throw something, or you shoot something : why doesn't it travel in a straight line forever? What makes it travel in an arc?

In that :

Then entire time said object is in the air - from the time it leaves my hand until it hits the ground - there is a direct relation between it's weight, the velocity it's travelling and the distance it is from the ground.

What is that relation, and why, no matter where along the distance the object travels you take a measurement, you get the same number of 9.2?

Here's where we find out that , yes, you probably also failed grade 8 math.

Here's another one :

Take a 10 gallon bucket and hook it up to a drill. Turn the drill on so the bucket spins for a few minutes. Then, take a few balls of different density ( size doesn't matter ) and throw them in the bucket.

After a few minutes : what do the balls do, and why? I'm asking you to explain centrifugal force on a flat earth that isn't spinning. I'll wait.
