Question
Explain why an object's weight can change while its mass remains the same.
Answer
An object's weight can change depending on the gravitational field strength acting on it, while its mass, which is the amount of matter in the object, remains constant. For example, an object weighs less on the Moon than on Earth due to the Moon's weaker gravitational pull, but its mass does not change.
Explanation
This question tests the understanding of the distinction between weight and mass, focusing on how weight is influenced by gravity. It assesses the student's ability to explain a fundamental concept in physics.
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).
