Question

1. what are the components of the unit of force, newtons? (hint: newtons 2nd law)

clear all
a $\frac{kgcdot m}{s^{2}}$
b $ncdot kg$
c $\frac{kgcdot m}{s}$
d $\frac{kgcdot m}{m}$

Explanation:

Step1: Recall Newton's 2nd law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. Mass has SI - unit of kilogram (kg) and acceleration has SI - unit of meters per second squared ($m/s^{2}$).

Step2: Determine the unit of force

Substitute the units of mass and acceleration into the formula for force. So, $F$ (in SI - units) has unit $kg\times m/s^{2}$.

Answer:

$\frac{kg\cdot m}{s^{2}}$ (assuming the first option in the image is $\frac{kg\cdot m}{s^{2}}$ as the others are incorrect based on Newton's 2nd law)
