    Do you know what a vector is?

    If not, then "magnitude of the acceleration" means the absolute value of the acceleration.

    i dont still get it
    could you do a simple example for me?
    is when you use pythagros theorem to find the magnitude?

    If there was an acceleration of 4m/s forwards, then the magnitude would just be the 4. If you have been given it in vector form (e.g. 4i + 3j[/j]) then Pythagorus would have to be used.
