When you're trying to measure how heavy something is or how much stuff is inside it, it's important to know that mass and weight are not the same.

Mass is all about how much material is in an object.

Weight is about how strong gravity pulls on that mass.

Let’s take a closer look at how we measure each one:

Measuring Mass

1. Balance Scale:
   • This kind of scale compares the mass of an object to known weights.
   • It’s very reliable and doesn’t change if you move it to a place with different gravity.
2. Digital Scales:
   • These are great for quick checks.
   • Just remember to set them up correctly before using!

Measuring Weight

1. Spring Scale:

   • This scale works by how much the spring pulls.
   • It’s useful, but it might not be as accurate as a balance scale.

2. Force Sensors:

   • In science labs, you might see high-tech sensors that can give you exact weight measurements in newtons (N).

Units to Remember

• Mass: Measured in kilograms (kg).
• Weight: Measured in newtons (N).

Keep these simple points in mind, and soon you'll be measuring like a pro!
