Question

which statement is accurate about mass or weight?
○ mass can be measured in newtons.
○ weight can be measured in pounds.
○ a bowling ball has the same mass as a golf ball.
○ objects have the same weight regardless of where they are.

Explanation:

• Mass is measured in kilograms (kg), grams (g), etc. Newton (N) is the unit of force (weight is a force). So, the statement “Mass can be measured in newtons” is incorrect.
• Weight is a force. Pounds (lb) is a unit of force (weight). So, the statement “Weight can be measured in pounds” is correct.
• A bowling ball has a much larger mass than a golf ball. So, the statement “A bowling ball has the same mass as a golf ball” is incorrect.
• Weight \(W = mg\) where \(g\) (acceleration due to gravity) changes with location (e.g., \(g\) on the moon is different from \(g\) on Earth). So, the statement “Objects have the same weight regardless of where they are” is incorrect.

Answer:

Weight can be measured in pounds.
