Mass and Weight

• Mass


  The amount of matter an object can contain
• Interia refers to the more mass an object hasthe more difficult it is to move.
• 1kg = 1000g

  1g= 1000mg
• Weight


  The downward force acting due to the pull of gravity on an object
• Weight is measured in newtons (N)
• Your mass remains the same no matter what planet you are on, but your weight can change depending on the planet
• Gravity


  A force that attracts things towards the centre of the Earth or any other body
• Inertia


  The more mass an object has, the more difficult it is to move
• Any object located in outer space is weightless
• Acceleration due to gravity in m/s²

  • Mercury: 3.6
  • Venus: 8.9
  • Earth: 9.8
  • Mars: 3.8
  • Jupiter: 26.0
  • Saturn: 11.1
  • Uranus: 10.7
  • Neptune: 14.1
  • Moon: 1.6
• Mass is the amount of matter an object has.
• Weight is the force that pulls objects to Earth's surface due to gravity.
• The weight of an object depends on its mass and the strength of gravity at the location where it is measured.
