Does everyone learn the same gravity in school or is it different everywhere?

So, I learned in physics class at school in the UK that the value of acceleration due to gravity is a constant called g and that it was 9.81m/s^2. I knew that this value is not a true constant as it is affected by terrain and location. However I didn’t know that it can be so significantly different as to be 9.776 m/s^2 in...

Going to guess civil. I work on space systems and we don’t have one number. We have the g0 value, which is standard gravity out to some precision, but gravity matters enough we don’t even use point mass gravity, we use one of the nonspherical earth gravity models. It matters because orbits.

“Smaller” if you’re a billionaire. When they say “the economy” just insert “rich people’s wealth”. It wouldn’t be a smaller economy in reality, because what drives a healthy economy is people spending money. Rich people don’t spend money, regular people do. Regular people getting paid more and having a larger piece of the pie, counterintuitively means there’s more pie.
