Objects are attracted to one another by the force of gravity. Gravity is proportional to the mass-the amount of matter-objects have; gravity decreases as the distance between the objects increases. An object's weight is a measurement of the Earth's gravitational pull on the object. What happens to the mass and weight of a rocket as it travels beyond Earth's orbit?

Correct answer: B. Its mass remains the same, and its weight decreases.

  • A. Its mass remains the same, and its weight increases.
  • B. Its mass remains the same, and its weight decreases.
  • C. Its mass decreases, and its weight decreases.
  • D. Its mass increases, and its weight remains the same.

Explanation

B is correct because weight is directly proportional to the gravitational force acting on an object, which decreases as the distance between the objects increases. As the rocket travels beyond Earth's orbit, it moves away from the gravitational pull of Earth, and therefore its weight decreases. However, the mass of an object remains constant, regardless of its location in space.
