Understanding the Concepts

* Weight: The force of gravity acting on an object's mass. Measured in Newtons (N).

* Mass: The amount of matter in an object. Measured in kilograms (kg).

* Acceleration due to gravity (g): Approximately 9.8 m/s² on Earth.

Formula

Weight (W) = Mass (m) × Acceleration due to gravity (g)

Solving for Mass

1. Rearrange the formula: m = W / g

2. Plug in the values: m = 94 N / 9.8 m/s²

3. Calculate: m ≈ 9.6 kg

Therefore, the mass of the rock is approximately 9.6 kilograms.
