Wow yesterday everyone on fj was a navy seal, the day before they were all theology professors, and today everyone's a physicist.
MFW I'm just a slacker eating doritos.

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"

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.

wouldnt the dress always be accelerating towards the floor? just the normal force from the lady is stopping it, so he must like the dress all the time, what a complimentive guy
