To be more precise, we are talking about the Earth's surface gravity, which is the acceleration due to gravity at the Earth's surface. It is approximately 9.81 m/s² (meters per second squared).
Here's how it works:
* Gravity is a force of attraction between objects with mass. The more massive an object, the stronger its gravitational pull.
* Earth's gravity is what keeps us on the ground. It also influences the tides and the orbits of satellites.
* Relative gravity is a way to compare the strength of gravity on different planets or celestial bodies. It is calculated by dividing the surface gravity of the other object by the surface gravity of Earth.
For example, the Moon's surface gravity is about 1.62 m/s², which is about 1/6th of Earth's gravity. So, the Moon's relative gravity is 0.16.
In summary, Earth's relative gravity is 1, and its surface gravity is 9.81 m/s².
