Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.

A little perspective

100 grams is about 1.11 times the mass of a boomerang.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • We use 90 g for the mass of a boomerang; the recorded range is 60 g–150 g.
  • The mass of a boomerang: This is an illustrative comparison value, not a claim that every example is the same.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.

Mass is distinct from weight: an object’s mass stays the same as gravity changes.
