Yes.
When the distance between the object's centers of mass increases, the force of gravity weakens (this can be measured experimentally on Earth at low elevations and high elevations with a sensitive pendulum and an accurate clock).
Mass does not change with changes in altitude or elevation. Weight on the other hand does change. However, on earth the change from sea level to the top of a mountain would be extremely small.
As altitude increases, the force of gravity gradually decreases. This decrease occurs because gravity depends on the distance from the center of the Earth; as you ascend, you move farther away from the Earth's center. However, the change is relatively small and becomes significant only at very high altitudes, such as those experienced in space. Overall, while gravity remains strong at high altitudes, it is slightly weaker than at sea level.
It is the other way round - gravity varies with altitude. In other words, you should consider altitude the independent variable. At a greater altitude, there is less gravitational force. This is explained by the equation - F(g) = G(m1m2)/(r^2) where G = constant, m1 and m2 = mass, F(g) = force due to gravity, and r = distance from center of mass. The altitude difference covered by humans daily (high buildings, hills) makes only a small, probably negligable difference in force due to gravity.
At an altitude of 40,000 feet (approximately 12,192 meters), gravity is slightly decreased compared to sea level, but the change is minimal. The acceleration due to gravity at this altitude is about 9.8 m/s², compared to approximately 9.81 m/s² at sea level. This represents a decrease of about 0.3%, which is not significant for most practical purposes.
Air pressure falls of as one gains altitude. At high altitude the air pressure is very low but it does not "falls drastically", which implies a sudden change.
Because of less gravity in high altitude

At high altitude; you are further away from Earth's centre of mass, so the distance is greater and the force due to gravity is lessened.

If you are moving at different altitude the gravity will changes and so the weght will changes

To calculate gravity at any altitude, you can use the formula: gravity at altitude = acceleration due to gravity at sea level * (1 - 2 * altitude / Earth's radius)^2. The acceleration due to gravity at sea level is approximately 9.81 m/s^2, and Earth's radius is roughly 6,371 km. Substituting these values will give you gravity at your desired altitude.

Acceleration due to gravity remains constant regardless of altitude. Other factors such as air resistance or the presence of external forces can impact acceleration at different altitudes.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
