Hello all,
i have some acceleration value s in each axis(x,y,z)
i want to calculate the acceleration and de-acceleration using the acceleration data in (m/s^2)

my data are as below:-
id time (ms) x (m/s2) y (m/s2) z (m/s2)
0 0 -0.1569064 7.4628606 5.9722495

How i will calculate the lateral and longitudinal acceleration (vehicle performance)

how to remove the gravity factor to get the acctual acceleration

thanks in advance

You need to provide a basic description of what it is you're doing here. If you want to remove gravity components you need to know the body orientation (Euler Angles), which I do not see.
