When we talk about weight and mass, it’s really important to know they are not the same thing.
Mass is the amount of material in an object. We measure it in kilograms (kg). The cool thing is, mass stays the same no matter where you are in the universe.
Weight is different. It’s the force of gravity pulling on that mass. We measure weight in newtons (N). Unlike mass, weight can change depending on the gravity of the planet you're on.
For example, on Earth, you can find weight with this formula:
Weight = Mass × Gravity
On Earth, the gravity is about 9.8 meters per second squared (m/s²).
Understanding the difference between mass and weight is really important.
This knowledge helps in many areas like engineering, sports, and even cooking!
By knowing these facts, we can build safe structures or help athletes perform their best.
