Chemists compared the atomic masses of isotopes to determine subtle differences in their structure.

In high-energy collisions, determining the rest masses of unstable particles requires precise reconstruction of their decay products.

In the simplified model, we treated the two point masses as if they were connected by a rigid rod.

The relativistic masses of particles increase with velocity, complicating calculations at speeds close to the speed of light.

Rising sea levels threaten to submerge low-lying land masses and the communities that depend on them.

Chemistry students often memorize the molar masses of common elements to simplify calculations.

In recent projects, we observed that only after reaching several critical masses did collaborative innovation truly take off.

After the storm, the beach was littered with wet masses of seaweed that clung to the rocks.

The laboratory recorded the dry masses of the samples after oven-drying them for 24 hours.

Historians warn that unchecked populism can give rise to tyrannies of the masses that silence minority voices.
