Mass
Definition
Mass refers to the amount of matter contained in an object, typically measured in units such as grams or kilograms. It is different from weight, which depends on gravitational force.
Analogy
Imagine you have two identical bags filled with marbles. If each bag has the same number of marbles, they have the same mass. Even if one bag looks bigger because it's fluffier, their masses are equal.
