Here's why:
* Gravitational force is the force of attraction between any two objects with mass.
* Weight is the force exerted on an object due to gravity. It's a measure of how strongly gravity pulls on an object.
It's important to distinguish between mass and weight:
* Mass is a fundamental property of matter and measures the amount of matter in an object. It remains constant regardless of location.
* Weight is a force that depends on both the object's mass and the strength of the gravitational field it's in.
For example, an object with a mass of 1 kilogram will have a different weight on Earth (where gravity is stronger) than it would on the Moon (where gravity is weaker).
