Question
Explain why weight is considered a vector quantity and provide an example of how it differs from mass.
Answer
Weight is considered a vector quantity because it has both magnitude and direction, acting downwards towards the center of the Earth. For example, an object with a mass of 10 kg has a weight of 98 N on Earth (assuming g = 9.8 N/kg), but its mass remains constant regardless of location, while its weight would change if it were on another planet with a different gravitational field strength.
Explanation
This question assesses the student's understanding of the distinction between vector and scalar quantities, specifically in the context of weight and mass. It encourages students to apply their knowledge to explain the concept clearly.
Common mistake
Confusing Weight and Mass
Students often confuse weight with mass, thinking they are the same quantity.
Remember that weight is a force measured in newtons (N) and depends on gravitational field strength, while mass is a scalar quantity measured in kilograms (kg) and does not change with location.
