The mass of a stone is measured on Earth and weighs 90 grams. The stone is then taken into space. Which of the statements below accurately describe the stone (are true)? Select all that apply.

Answer 1

To assess what can be said about the stone when it is taken into space after having been weighed on Earth, we can consider a few key factors regarding mass and weight. Here are some statements that may apply:

1. The mass of the stone remains unchanged. - This statement is true. Mass is a measure of the amount of matter in an object and does not change regardless of location.

2. The weight of the stone decreases in space. - This statement is true. Weight is the force exerted by gravity on an object. In space, especially far from gravitational influences, the weight of the stone would be significantly less than it is on Earth.

3. The stone still has a mass of 90 grams even in space. - This statement is true. The mass of the stone would still be 90 grams, regardless of its location.

4. The stone will float or appear weightless in space. - This statement is generally true. In the absence of significant gravitational forces, the stone would appear to float and may be considered weightless.

5. The stone's density changes in space. - This statement is false. The density of the stone, being a ratio of mass and volume, remains the same unless the stone changes in mass or volume.

In summary, the true statements are:

• The mass of the stone remains unchanged.
• The weight of the stone decreases in space.
• The stone still has a mass of 90 grams even in space.
• The stone will float or appear weightless in space.
