The gravitational force on an object near the Earth's surface is called weight. It's calculated using the following formula:

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

Here's a breakdown:

* Mass (m): The amount of matter in an object, measured in kilograms (kg).

* Acceleration due to gravity (g): The acceleration experienced by an object due to Earth's gravitational pull, approximately 9.81 meters per second squared (m/s²).

Important Note:

* This formula assumes the object is near the Earth's surface. As you go further away from Earth, the gravitational force decreases.

* This force is directed towards the center of the Earth.
