explain what gravity accellation is when they say 9.8m/s/s?

Answer 1

m/s/s is meters per second per second.

so every second (the second s) the speed (m/s) increases 9.8

so one second, speed is 9.8m/s, 2 seconds 19.6m/s...

Answer 2

Okay....written out in words it is 9.8 meters per second per second. This means that it is doubling every second. So, something begins falling and in the first second we already have our answer: 9.8 meters. In the next second, it will fall twice that which would be 19.6 meters. Here comes the reason for the per second per second...or why it repeats itself. you must ADD second #1's distance to second #2's distance so in 2 seconds our object has fallen a TOTAL of 29.4 meters. If we added a third second, we would now double the 19.6 which would be 39.2 meters. And so, adding all of it together it has fallen-in 3 seconds time-a TOTAL of 9.8+19.6+39.2 meters which is actually 68.6 meters. And so on until infinity or if a term Terminal Velocity is introduced, that means that, without any extra help, this object can only fall so fast or so many meters per second after a while. For example, on Earth, I believe it is somewhere around 200 feet per second. But please don't include this into your calculations as this is based on feet and not meters and the rate of descent is 32f/s/s which calculates NOT to 9.8 but 9.75. So everything would be off. Just stick with your 9.8 meters if that is what you are told to use. I hope I have explained it okay and not confused things to badly.

Answer 3

Its actually 9.8 meters per second squared. Or 96.04 meters per second.

Its easier to keep the squared around for dealing with the math.

So in one second you fall 96.04 meters almost 300 feet.

Answer 4

well, it's also referred to as 9.8 m/s^2. so you can think of it as accelerating at 9.8 m/s every second.

that made sense in my head - but im not so sure it makes sense typed out... hope \fully it helped?
