Weight vs Mass

Weight

Weight is the force exerted by gravity on an object. It varies depending on gravitational field strength.

  • • Measured in Newtons (N) scientifically
  • • Commonly expressed in pounds or kilograms
  • • Changes with location (Earth vs Moon)
  • • Depends on gravitational acceleration

Mass

Mass is the amount of matter in an object. It remains constant regardless of location.

  • • Measured in kilograms (kg) scientifically
  • • Fundamental property of matter
  • • Constant throughout the universe
  • • Used in physics calculations
