MASS, WEIGHT AND GRAVITY

• What is gravity?


  The force of attraction between all masses
• What is weight?


  Weight is caused by the pull of gravity. The weight of an object is just the force of gravity pulling it towards the centre of the earth. It will change.
• What is mass?


  Mass if just the 'amount of stuff' in an object. This will have the same value anywhere in the universe
• How are mass and weight different?

  An object will have the same mass whether it's on the earth or the moon but its weight will be different.
• Will a 1kg mass weigh the same on the moon as it does on the earth?

  It will weigh less on the moon because the force of gravity is less
