What is the difference between mass and weight of an object?

Mass is a measure of how much stuff is in an object and weight is a measure of how heavy an object is due to the force of gravity acting on it.

Mass is the amount of matter in an object and it stays the same no matter where you are, while weight is how much gravity pulls on an object and it changes depending on the strength of gravity.

Sure! Mass is the amount of matter in an object, like how much stuff is in it, while weight is the force of gravity pulling on that object, like how heavy it feels.
