The mass or the amount of matter in something determines how much energy that thing could be changed into.

The atomic masses of naturally occurring isotopes of an element determine the atomic mass of the element.

A particle's mass, density, and shape will determine its S value.

If superpartners are found, its mass would determine the scale at which supersymmetry is broken.

And the mass of that particular piece of debris again determined based on the density of that size of debris.

Luminous X-ray bursts can be considered standard candles, since the mass of neutron star determines the luminosity of the burst.

The inertial mass of an object determines its acceleration in the presence of an applied force.

A body's mass also determines the degree to which it generates or is affected by a gravitational field.

The mass of a body determines the momentum of the body at given velocity ; it is a proportionality factor in the formula:
