If you move away from the Earth, you will eventually stop accelerating due to the gravitational force exerted by the Earth diminishing as you move farther away. The gravitational force between two objects decreases with distance according to the inverse square law.
When you are close to the Earth's surface, the force of gravity is relatively strong, and you experience an acceleration due to gravity. This acceleration is what we commonly refer to as "falling" or "being pulled" toward the Earth. However, as you move away from the Earth, the distance between you and the Earth's center increases, resulting in a decrease in the gravitational force acting on you.
According to the law of universal gravitation, the magnitude of the gravitational force (F) between two objects is given by:
F = (G * m1 * m2) / r^2
Where: G is the gravitational constant, m1 and m2 are the masses of the two objects (in this case, your mass and the Earth's mass), and r is the distance between the centers of the two objects.
As you move away from the Earth, the value of r increases, which means the denominator of the equation (r^2) increases. Consequently, the gravitational force F decreases. Since your acceleration due to gravity is directly proportional to the gravitational force, your acceleration will gradually decrease as you move farther from the Earth.
Eventually, at a certain distance, the gravitational force becomes negligible compared to other forces acting on you (such as the gravitational forces from other celestial bodies). At this point, you would effectively stop accelerating due to the Earth's gravity. However, it's important to note that there are other factors in space, such as the gravitational influence of other celestial bodies, that can still affect your motion.
