Here's why:
* Gravity: A force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull.
* Weight: The force of gravity acting on an object's mass. It's measured in units like Newtons (N) or pounds (lbs).
Important Note: Weight is not the same as mass!
* Mass: A measure of the amount of matter in an object. It's a fundamental property and remains constant regardless of location.
* Weight: Depends on both the object's mass and the gravitational field it's in. For example, an object on the Moon would have less weight than on Earth because the Moon's gravity is weaker.
