# What is inertia mass?

Mar 12, 2018

#### Explanation:

Inertial mass is the measurement in which how difficult it is to change the velocity of an object.

Using Newton's second law, stating the formula:

$F = m a$ where F is force, $N$, M is mass in $k g$, and A is acceleration in $m / {s}^{2}$

This, therefore, can be re-arranged to find out the mass:

$m = \frac{f}{a}$
