What is the fundamental difference between the mass of an object and its weight?
Answer and explanation
Correct answer: B. Mass is the quantity of matter in an object
- Step 1: Mass is an invariant scalar quantity measuring the amount of substance (measured in kg). Step 2. Weight is a downward vector force dependent on local gravitational field strength (measured in N). Answer: Mass is the quantity of matter in an object. Why not the others: Mass is measured in kg, weight in N; mass is constant while weight changes on other planets; mass is scalar, weight is vector.
