What does magnitude of acceleration mean?

[rachael]

what does "what is the magnitude of the accelaration" means?



thank you

Do you know what a vector is?

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

 

[rachael]

i don't still get it
could you do a simple example for me?
is when you use pythagros theorem to find the magnitude?

 

[Libertine]

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.
