Answer: 9.8 meter per second square
Notes: The mean value of the acceleration due to gravity (often denoted as "g") at Earth's surface is approximately 9.81 meters per second squared (m/s²). This value represents the average gravitational acceleration experienced by objects on the surface of the Earth. It is important to note that this value is not constant everywhere on Earth's surface and can vary slightly due to factors such as location, altitude, and the density of the Earth's crust.
