The gravitational pull *on* Earth is determined by the mass of the Earth and the distance from its center. The force of gravity is what keeps us on the ground and what causes the moon to orbit the Earth.

Here's what you need to know:

* Acceleration due to gravity (g): This is the standard measurement of Earth's gravitational pull. It's approximately 9.81 meters per second squared (m/s²). This means that for every second an object falls, its speed increases by 9.81 meters per second.

* Factors affecting gravity: Gravity is affected by:

* Mass: The more massive an object, the stronger its gravitational pull.

* Distance: The further away you are from the center of an object, the weaker its gravitational pull.

It's important to note that the value of "g" varies slightly depending on your location on Earth due to factors like altitude and the density of the Earth's crust.
