Mass vs. Weight: Are They the Same? (Spoiler: Nope!)

Ever wondered about the difference between mass and weight? They're often used interchangeably, but they represent distinct concepts!

**Mass** is a measure of how much "stuff" is in an object. It's a fundamental property and remains constant regardless of location. Think of it as the amount of matter you're made of. Measured in kilograms (kg) or grams (g).

**Weight**, on the other hand, is the force of gravity acting on an object's mass. It depends on the gravitational pull of the celestial body you're on. You weigh less on the moon because the moon has weaker gravity! Weight is a force, measured in Newtons (N).

So, you might weigh different amounts on Earth and Mars, but your mass stays the same. Think of it this way: mass is *what you are*, weight is *how much gravity pulls on you*. Understanding this difference is key to grasping fundamental physics!
