* Mass is the amount of matter in an object. It's an intrinsic property and remains constant regardless of location. Think of it as the "stuff" that makes up the object.
* Weight is the force of gravity acting on an object's mass. It's a measure of how strongly gravity pulls on an object.
Here's the key point:
* Gravity determines weight, not mass.
Example:
* You have the same mass on Earth as you do on the moon. Your body contains the same amount of matter.
* However, you weigh less on the moon because the moon's gravity is weaker than Earth's gravity. The force pulling on your mass is less.
In summary:
* Mass: A fundamental property of an object, independent of gravity.
* Weight: A force determined by gravity acting on an object's mass.
