Mass
The amount of matter in an object.
Video: Mass simple definition.
Imagine you're packing a suitcase for a vacation, trying to decide how much you can fit inside. Just like you assess the contents of your suitcase to determine if it’s over the airline's weight limit, mass measures the amount of matter within an object. The weight of your packed suitcase represents its mass; every item you add is like adding more matter, increasing the suitcase's mass, just as each particle contributes to an object's total mass.
