How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The weight of a 180 g apple: This is an illustrative comparison value, not a claim that every example is the same.
Weight is gravitational force; the same mass weighs differently where gravity changes.
