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
