I assume you mean when the acceleration of gravity stops altering the velocity of a falling object. At this point the force of air friction is equal but opposite to the force of gravity, velocity stops increasing in magnitude. This is called "terminal velocity."
Terminal Velocity
That is the object's terminal velocity.
Speed or acceleration have no effect on gravity.
That would be balanced, because the motorboat is not increasing in speed or decreasing in speed.
When a system is in isostasy, downward gravity and upward buoyancy are balanced.
Terminal Velocity
You must calculate using the speed of gravity as instantaneous otherwise a balanced moving mass system is no longer balanced and is out of alignment.
That is the object's terminal velocity.
Gravity((:
terminal velocity
In the case of a star (that is not actually going nova or supernova) they are balanced.
a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).
It is balanced by radiation pressure, and gas pressure.
Speed or acceleration have no effect on gravity.
well, we are moving at a constant speed(the earth's rotation) and everything else in the universe is as well because of the effects of gravity, so either nothing can be balanced because everything is moving, or plenty of things can be. I guess this depends on your definition of the word balance.
Speed is relative to the speed of light and gravity. So gravity could effect speed.
That would be balanced, because the motorboat is not increasing in speed or decreasing in speed.
