In addition to acceleration, what do you need to know to calculate inertial mass?

To calculate inertial mass, in addition to acceleration, you need to know the net force acting on the object. Here’s a breakdown of the essential concepts:

1. Newton's Second Law of Motion: This law states that the force $F$ acting on an object is equal to the mass $m$ of the object multiplied by its acceleration $a$. This can be expressed with the formula: $F = m \cdot a$

2. Rearranging the Formula: If you want to find the inertial mass $m$, you can rearrange the formula: $m = \frac{F}{a}$ Here, $F$ is the net force acting on the object, and $a$ is the acceleration.

3. Understanding Net Force: It's critical to understand what is meant by the net force. This is the total force resulting from all individual forces acting on the object, taking into consideration their directions.

In conclusion, to determine the inertial mass of an object, you need to have the net force applied to it and its acceleration. By applying these values to Newton's second law, you can calculate the inertial mass effectively.
