This is a mini space where you could refresh things you know as I hopefully believe you are already interested in Physics,therefore this space dosent cover the subject. The primary objective is to help you do well in the exam.
Using a set mass of one object (eg 100g of water) change the space its in (eg 200ml cylinder taking ten off the ml each time.) Use the formula mass/volume to find the density, it will go up as the volume decreases.
