Understanding the Concepts

* Newton's Second Law of Motion: This law states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a). Mathematically, this is expressed as: F = ma

* Units:

* Force is measured in Newtons (N)

* Mass is measured in kilograms (kg)

* Acceleration is measured in meters per second squared (m/s²)

Solving for Mass

1. Identify the knowns:

* Force (F) = 30 N

* Acceleration (a) = 3 m/s²

2. Rearrange the formula to solve for mass (m):

* m = F / a

3. Plug in the known values:

* m = 30 N / 3 m/s²

4. Calculate the mass:

* m = 10 kg

Therefore, the mass of the object is 10 kg.
