General relativity says that gravity is nothing more than the inertial effects of curved space. I'm having trouble visualizing that in day to day experiences.

Einstein would say that the ball is following the shortest path in space time. I realize that doesn't help much. Regular old force of gravity is easier to grasp!
Space-time is bent by the earth's gravitational field. We see the space part as pretty flat, but we are following a "curve" as we are held in place by the surface of the earth. Einstein would say we can tell we are following a curve because we are accelerating and acceleration implies a change in direction!!
Hope that helps!

Space curves near gravitional fields, not the gravity of the Earth pulling down on a ball. Ask Newton not Einstein.

Einstein would explain that the energy used to cause the ball to raise 5 feet, is cancelled out by gravity at the 5 ft. mark, and gravity forces the ball to fall back toward the earth.

Einstein will refer this question to Newton

Your problem is one of classical mechanics, which relativity degenerates to in the absence of very large masses or speeds.

I'm pretty sure he'd say you throw like a girl. :)
Kidding, here's a good Einstien site. Might find your answer there.
