Questions and Answers

What is the difference between mass and weight?

Mass is a measure of the amount of Earth's attraction to a body, while weight is the amount of matter in an object.

Mass is the amount of matter in an object, while weight is a measure of the quantity of molecules in a solid body.

Mass does not change, but weight can vary depending on the location, such as on the moon or different planets. (correct)

Mass is measured in newtons, while weight is measured in grams or kilograms.

How do scientists measure the mass of an object?

By observing the amount of space occupied by the object.

By measuring the quantity of molecules in the body.

By comparing it to standard masses using balances. (correct)

By using spring scales and measuring it in kilograms.

Why do objects weigh less on the moon compared to on Earth?

Objects weigh the same on the moon as they do on Earth.

Because the moon's gravitational force is stronger than Earth's.

Because the Moon's mass is less than Earth's, resulting in less gravitational force on objects. (correct)

Due to the moon having more mass than Earth.
