Question

A. In the book on table scenario, apply weight to explain why an object's weight can change while its mass remains the same while keeping mass versus weight separate.
B. In the book on table scenario, mix up mass versus weight and ignore weight.
C. Use a general revision statement without applying Gravity and weight to the situation.
D. Choose a different forces topic instead of explaining explain why an object's weight can change while its mass remains the same.

Answer

The correct answer is: In the book on table scenario, apply weight to explain why an object's weight can change while its mass remains the same while keeping mass versus weight separate.

Explanation

The correct option is In the book on table scenario, apply weight to explain why an object's weight can change while its mass remains the same while keeping mass versus weight separate.. It is correct because the scenario says weight and normal contact force act on one object, which must be interpreted through Gravity and weight. This directly supports the learning objective to explain why an object's weight can change while its mass remains the same. Use values 6, 11, and 10 only if the question asks for a calculation. The answer earns credit by naming the relevant force or motion quantity, using units when needed, and avoiding the boundary error mass versus weight.

Common mistake

Weight vs Mass Confusion

Students often confuse weight with mass, thinking they are the same quantity.

Remember that mass is a measure of the amount of matter in an object (measured in kilograms), while weight is the force acting on that mass due to gravity (measured in newtons).
