Thanks for that, I appreciate your reply ... Let me give you a bit more meat around the problem I'm investigating. Let's imagine that we have some apparatus that can eliminate 99.9% of 'g'; let's call it an anti-gravity machine ... But, let's first imagine that the gravitational acceleration...
Imagine a ball being tossed into 'the air'. At its peak, the ball has a velocity of 0(m/s), but how long does it actually have this velocity for? --> Neglecting the effects of air-resistance.
Obviously the ball undergoes constant 'g' the whole time, but the answer to my question doesn't relate...
