Not really sure about these units

[kenhung123]

Why is it that in gravitation g=N/kg not m/s^2?

[m@tty]

They are the same.

They are the same.

So they can be used interchangeably? I can say g=10ms^-2 and a=10N/kg? because usually in answers they state g units as N/kg and a units as ms^-2

Yes, just like how Ns is equivalent to kg m/s [momentum]

is usually used when describing the gravitational field.

The gravitational field is 'force per unit mass', so the 'field' is defined so that

Likewise, the electric field is 'force per unit charge', so the field is defined by , and the units are

Just another way of looking at what 'g' means.
