## Explanation

The measure of the amount of gravity pulling on an object is referred to as its **weight**. Weight is essentially the force exerted by gravity on an object. The formula to calculate weight can be expressed as:

Where:

- $\mathbf{W}$ is the weight,
- $\mathbf{m}$ is the mass of the object,
- $\mathbf{g}$ is the acceleration due to gravity.

### Understanding the Components

**Mass (m)** is the quantity of matter in an object, measured in kilograms (kg). It is important to note that mass remains constant regardless of the object's location.

**Acceleration due to gravity (g)** is the rate at which objects accelerate towards the Earth. The standard approximate value is:

This value can slightly vary depending on the location (e.g., altitude, latitude) but is usually considered consistent for most practical purposes.

### Key Takeaway

Weight can change depending on the gravitational force exerted by another celestial body. For example, an object will weigh less on the Moon than on Earth due to the Moon's weaker gravitational pull. This distinction highlights that **weight is dependent on both mass and the local gravitational field**, making it different from mass, which is an intrinsic property of the object.
