To solve this problem, we need to understand the difference between
mass and
weight, and then match each picture to the correct concept.
---
Step 1: Understand what mass is
-
Mass is how much “stuff” (matter) is in an object.
- It does NOT change depending on where you are — whether on Earth, the Moon, or in space.
- We measure mass using tools like a
balance scale (the seesaw-like tool with two pans).
- Units for mass: grams (g), kilograms (kg).
→ The left image shows a
balance scale. That’s used to compare masses. So it belongs under
MASS.

Step 2: Understand what weight is
-
Weight is how hard gravity pulls on an object’s mass.
- Weight CAN change — for example, you weigh less on the Moon because gravity is weaker there.
- We measure weight using tools like a
spring scale or a
digital scale that shows force (like pounds or newtons).
- The right image shows a digital display reading “31” — this looks like a bathroom scale or digital weighing scale, which measures
weight (force due to gravity).
→ So the right image belongs under
WEIGHT.
---
Step 3: Double-check
- Balance scale → compares mass → MASS column
✔
- Digital scale showing number → measures pull of gravity → WEIGHT column
✔
No calculations needed here — just matching concepts to tools.

Final Answer:
MASS: balance scale (left image)
WEIGHT: digital scale (right image)
