Understanding the Concepts

* Force (F): Measured in Newtons (N). It's a push or pull on an object.

* Mass (m): Measured in kilograms (kg). It's the amount of matter in an object.

* Acceleration due to Gravity (g): On Earth, this is approximately 9.8 m/s². It's the rate at which objects accelerate towards the Earth's center.

The Formula

The relationship between force, mass, and acceleration is given by Newton's Second Law of Motion:

* F = m * g

Solving for Mass

1. Rearrange the formula: To find the mass (m), we need to isolate it:

* m = F / g

2. Plug in the values:

* F = 98 N

* g = 9.8 m/s²

3. Calculate:

* m = 98 N / 9.8 m/s² = 10 kg

Answer: The mass of a 98 Newton object on Earth is 10 kilograms.
