Question

f=ma so f is force
m=mass so that must be in nweton is this correct

Answer 1

N = kg*(m/s^2)

Answer 2

International measure system (SI) is stating that mass m has basic unit of 1 kilogram Kg.
Force F is measured in Newton N and is connected with other measures by m*kg*s^-2

Answer 3

check out this document. http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf
look at page 24-27.

Answer 4

F = ma - that's correct.

F is force, measured in Newtons (N).
m is mass, measured in kilograms (kg).
a is acceleration, measured in meters per second squared (m / s^2).

N = (kg) * (m / s^2)

Answer 5

the fundamental of newton is NOT F=MA this is used when m and a is constant, if there aren't constant so you must put this F=dP/dT
