what does density mean in an easy way..!
Density is the amount of matter contained within an object. For instance, a cannonball would have more density than a ping pong ball. Does this make sense?
Density is mass/unitvolume. for instance the density of water is approximately 1000 grams per Liter. So in one liter of space there is 1000 grams of water.
