Description
| Question | Answer |
| Mass is NOT the same as weight. | Mass is defined as: "The amount of matter in an object" |
| Mass is measured in kilograms (kg) | A water balloon is more massive than an air balloon; there is more matter (water) in the water balloon |
| The mass of an object never changes (unless we alter the object)! | Weight is a force caused by gravity pulling on a mass |
| Weight is a measure of how heavy an object is and it always acts towards the centre of the planet | As the size of gravity changes so does the weight |
