Question 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

1 answer

To determine which statements accurately describe the stone, we can consider the properties of mass and weight.

  1. The mass of the stone remains the same: This statement is true. The mass of an object does not change regardless of its location. Therefore, the stone still has a mass of 90 grams in space.

  2. The weight of the stone becomes zero in space: This statement is generally true. Weight is the force exerted on an object due to gravity. In outer space, away from significant gravitational influence, the weight of the stone would effectively become negligible, so it would not have a weight in the same way it does on Earth.

  3. The stone's density does not change: This statement is true. Density, which is mass per unit volume, remains constant as long as the object's volume doesn't change. Since we have not mentioned a change in the stone's physical state, its density remains the same.

  4. The stone experiences a different gravitational force in space: This statement is true. The stone will experience a different gravitational force in space, which is typically much weaker than that on the surface of the Earth.

Given these considerations, the true statements about the stone when taken into space are:

  • The mass of the stone remains the same.
  • The weight of the stone becomes zero in space (or negligible).
  • The stone's density does not change.
  • The stone experiences a different gravitational force in space.

You would select all of these as true statements regarding the stone in space.
