Understanding Mass: Grams and Kilograms
What is Mass?
Mass tells us how much matter (or "stuff") is in an object. Everything around you has mass - your pencil, your backpack, even you!
Fun Fact: Mass stays the same no matter where you are - on Earth, on the Moon, or in space!
Mass vs. Weight: What's the Difference?
Mass
- How much matter is in something
- Always stays the same
- Measured in grams (g) and kilograms (kg)
Weight
- How heavy something feels
- Changes in different places (Earth vs. Moon)
- Measured in pounds or newtons
Simple way to remember: Mass is about the "stuff" inside. Weight is about how gravity pulls on that stuff!
