Summary
Mass is how you describe how heavy an object is. You can compare the weights of objects using mass and you can use a weighing scale or balance to find and compare masses of objects.
Heavier objects have greater mass, so a pot is heavier than a fork. Remember that you can only compare masses if they have the same unit; a book is not heavier than a chair! Use this equation to convert between units:
1. | Make sure the units are the same. |
2. | Identify what the question is asking you:
|
3. | Convert the answer back into appropriate units (if required). |
