Question

what is the difference between mass and weight?

Explanation:

Mass is the amount of matter in an object (scalar, constant), while weight is the force of gravity on an object (vector, varies with gravity). Mass is measured in kg, weight in N (or kg·m/s²).

Answer:

Mass is the quantity of matter in an object (constant, scalar, measured in kg), weight is the gravitational force on an object (varies with gravity, vector, measured in N).
