Mass vs Weight — Comparison Table

BasisMassWeight
DefinitionAmount of matter in an objectForce exerted by gravity on mass
NatureScalar quantityVector quantity
SI UnitKilogram (kg)Newton (N)
DependenceDoes not depend on locationDepends on gravity (g = 9.8 m/s²)
MeasurementBalance scaleSpring scale

Key Points

  • Mass is intrinsic and constant; weight varies with gravitational field strength
  • An astronaut has same mass on Earth and Moon, but different weight
  • Weight = Mass × Gravitational acceleration (W = mg)
  • Mass never changes; weight changes on different planets and altitudes
