Is it m/s2 or m/s-2
It is m/s2 or ms-2.
The / sign means that it is metres divided by seconds squared.
ms-2 is the same and the reason is because of indices. s-2 means that seconds are under metres and the 2 means that this figure is squared.
Do not write m/s-2 that is not right!
My teacher kept writing m/s-2 in notes on the board , but in this revision guide i have it says m/s2 so i was just wondering?
Sorry i wrote it wrong i meant is it measured in ms2 or ms-2?
Oh yeah that makes more sense - I thought that maybe your teacher was awful!
Haha, ( he still is awful but not for that reason! )
m/s2 is the old way to write it but ms-2 is the new way
