Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Weight?Weight (W) = mass (m) × acceleration due to gravity (g)
2. What is the gravitational acceleration?Earth's surface gravity (g) is approximately 9.8 m/s²
3. What is the historical measurement?Steelyard balances were an early portable method for weighing
4. What is the difference between weight and mass?Mass is the amount of matter in an object and stays the same no matter where it is. Weight is the force that gravity pulls on that mass, so it can change if gravity changes.
5. Why do astronauts weigh less on the Moon?The Moon’s gravity is weaker than Earth’s, so the same mass feels lighter there. That’s why astronauts can jump higher and lift objects more easily on the Moon.

Mass: A fundamental property of matter representing the amount of substance in an object.
Gravitational Force: The attractive force exerted between any two objects with mass.
Spring Scale: A weighing instrument that measures force based on the extension of a spring.
Load Cell: A transducer that converts force into a measurable electrical signal, used in electronic scales.
