Wow yesterday everyone on fj was a navy seal, the day before they were all theology professors, and today everyone's a physicist.

mfw people think they're scientists by knowing this.
I learned this when i was 14, and i didn't have an interest in physics.

My science hurt when reading everyone trying to sound like they're smart for realizing this is gravity and for trying to correct the quote by saying "It's actually -9.8m/s^2"

If you're going to be a a fag OP, at least post one that doesn't have black bars...

Some 8th grader on a youtube comment yesterday tried to tell me that I'm dumb because I think that objects actually fall in a vacuum. Nevermind me mistakenly believing that all things fall at 9.8 m/s....-cough- Sorry, it's hard to breathe with this palm so firmly planted on my face.

:D Hey I actually know what 9.8 m/s squared stands for now! ( In my first physics class )

The gravitational accelartion earth varies on earth from 9.78m/s^2 to 9.82 m/s^2. Why?
The earth isn't perfectly round, and so the force lf gravity can be stronger or weaker depending on where you are.
Thus, gravity has an uncertainty of plus/minus 0.02, and therefore, gravity is usually written as 9.8m/s^2 with only two significant figures

As gravity is a vector quantity, it has a magnitude and direction. Because of so, the g can never be a negative quantity; -9.8m/s^2, as some people say. The reason that a lot of people here are confused is because of the direction of the acceleration. This is where the Cartesian coordinates comes in handy.

Imagine a coordinate. When the dress hits the floor, nor the time of impact does not matter, so we will only use a vertical axis to represent the fall of the dress and call it the y-axis.
When the dress falls, the acceleration is downwards, in the negative y-direction. Thus, g itself is negative and -g=9-.8m/s^s is correct, not g=9.8m/s^2.

In conclusion, the gravitational force on earth is ALWAYS a positive value equal to 9.8m/s^2, due to the uncertainties and it being a vector quantity.

actually i hate to brake it to you but gravity is 9.81 m/s2, it makes all the difference when working on the space shuttle

You're thinking in terms of distance. Yes, you would use negative for distance calculations, but when it is falling towards the ground it is GAINING speed, which means it has positive acceleration. If it were to fall with a negative acceleration, it would slow down.
