The force caused by gravity pulling down on an object causes it to have weight.

Here's a breakdown:

* Gravity: A fundamental force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull.

* Weight: The force exerted on an object due to gravity. It's a measure of how strongly gravity pulls on that object.

Example:

You feel heavier on Earth than on the Moon because Earth has a stronger gravitational pull. This means you experience more weight on Earth.
