Question

what is the unit of force? Is it kgm/s or N? help i'm confused.....

Answer 1

N

Answer 2

One Newton is defined as one kg.m/s^2

1 N = 1 kg.m/s^2

Answer 3

ok but there is this physics problem concerning the force of a bacteria....my teacher's answer was in kgm/s but most of the students in the class put N! what to do?

Answer 4

I'm sure he/she meant to write kg.m/s^2, as kg.m/s is NOT a unit of force.

Answer 5

ok then i will write it your way..is it 2 or -2?

Answer 6

\[ \frac{kg.m}{s^2} = kg.m.s^{-2} \]
This comes from Newton's second law,
\[ F = ma \]
The units of mass, m, is kg. The units of acceleration a, is m/s^2. Hence the units of force is

kg.m/s^2

Answer 7

excellent!! thank you!
