Understanding the Concepts

* Weight: The force of gravity acting on an object's mass.

* Mass: The amount of matter in an object.

* Newton's Second Law: Force (F) = Mass (m) x Acceleration (a)

Calculation

1. Acceleration due to gravity (g): On Earth, the acceleration due to gravity is approximately 9.8 m/s².

2. Rearrange Newton's Second Law: We know the weight (force) and the acceleration due to gravity, so we can rearrange the formula to find the mass:

* Mass (m) = Force (F) / Acceleration (a)

3. Plug in the values:

* m = 14.7 N / 9.8 m/s²

* m = 1.5 kg

Therefore, the mass of the book is 1.5 kilograms.
