On average, the acceleration of an object falling to Earth due to gravity is around 9.8 meters per second squared. But in places with more or less gravity, that acceleration may be slightly different.
At Earth's surface, the acceleration due to gravity is about 9.8 m/s 2; that is, with every second that passes, the downward speed of a falling object increases by 9.8 m/s 2.
So, you know how we've been describing the gravitational acceleration at Earth's surface as small g? Well, small g is actually equal to big G, times Earth's mass, divided by Earth's radius, squared.
"That is weight is equal to mass times gravitational acceleration. Weight is not measured in kilograms, but in Newtons. "For example the gravitational acceleration for everyone standing on Earth ...
Finally, the Earth moves a little bit beyond one complete revolution, so the stick again points towards the sun for a second local noon. The sidereal day is just a little bit shorter—approximately 23 ...
So the very simple answer to the question is "the gravitational pull on the Earth is (the force that causes) an acceleration of approximately 9.8 m/s/s." Actually, this acceleration g isn't truly ...
I had an interesting thought, spurred on by a discussion I ran across online about firing guns in space. Apparently, smokeless powder contains its own ...

Generally, it's estimated that Earth's gravitational acceleration - the 'force' that gravity pulls you towards the centre of the planet - is 9.8 m/s². However, ...
