How strong is acceleration due to gravity ?
For example at the periphery at a galaxy ?

Acceleration due to gravity in a galaxy is a measure of how fast objects within the galaxy are pulled towards its center. It is caused by the mass of the galaxy and can vary depending on the distance from the center and the mass distribution within the galaxy.
Acceleration due to gravity in a galaxy is different from Earth's gravity because it is not a constant value. Earth's gravity is relatively consistent at 9.8 meters per second squared, while in a galaxy, it can vary greatly depending on the location and mass distribution within the galaxy.
The main factors that affect acceleration due to gravity in a galaxy are the mass of the galaxy and the distance from its center. The distribution of mass within the galaxy can also play a role in determining the strength of gravity.
Acceleration due to gravity in a galaxy is typically measured using astronomical observations and mathematical calculations. Scientists can observe the movement of objects within a galaxy and use equations, such as Newton's Law of Universal Gravitation, to determine the acceleration due to gravity.
Yes, acceleration due to gravity in a galaxy can change over time. This is because the mass and distribution of mass within a galaxy can change due to the movement and interactions of stars and other celestial bodies. However, these changes are usually very gradual and may not be noticeable within a human lifetime.
