* Mass vs. Weight: Mass is a fundamental property of an object that measures how much matter it contains. Weight, on the other hand, is the force of gravity acting on an object's mass.
* Gravity's Role: Gravity exerts a force on objects, pulling them towards each other. The strength of this force depends on the mass of the objects involved and the distance between them.
* No Mass Change: Gravity doesn't change the amount of matter in an object, so it doesn't alter its mass.
Think of it this way:
* You have the same mass on Earth as you do on the Moon, even though you weigh less on the Moon because the Moon has weaker gravity.
Key Takeaway: Gravity affects an object's weight (the force it experiences), but it doesn't change its mass (the amount of matter it contains).
