Does everyone learn the same gravity in school or is it different everywhere?
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 Kuala Lumpur for example. I'm wondering if a different value is told to children in school that is locally relevant for them? Or do we all use the value I learned?
You're viewing a single thread.
I've learned it as 9.81 but we usually round up to 10 for calculations. (this is for highschool. I haven't gotten to college yet)
We just use 9.8 at my high school for calculations. Also its cool to see another young person on the fediverse (Assuming you are still in highschool).
Close enough I graduated last year 2023. I couldn't get in to the college I wanted so I decided to try it a second time. There's a countrywide exam that gives you a score. It's called yks. I'm currently studying for that exam.
You round it to 10? Do you also round PI to 3 for simplicity? Kids these days.
Rounding of constants always depends on what you are calculating. Getting a rocket into orbit is a case to use the actual local value of g with a bunch of digits (and the change with height, too). If you build a precision tool, some more digits of PI are no bad idea.
But to calculate the lenght of fence to buy to surround a round pond, I actually used 10/3 for "PI plus safety margin" once.
I was just kidding but good example with the fence.
yeah :/ in physics class we do round pi to 3
