key term - Mass

Definition

Mass is a measure of the amount of matter in an object and is typically measured in kilograms. It is a fundamental property that influences gravitational attraction and inertia.

5 Must Know Facts For Your Next Test

  1. Mass remains constant regardless of an object's location in the universe.
  2. Newton's law of gravitation states that two masses attract each other with a force proportional to their product and inversely proportional to the square of the distance between them.
  3. In astronomy, stellar mass determines a star's lifecycle, luminosity, and spectral type.
  4. Binary star systems are crucial for measuring stellar masses through their gravitational interactions.
  5. Mass is distinct from weight, which varies based on gravitational strength at different locations.
