1. on planet Y
2. Mass is the same everywhere. Weight depends on the force of gravity.
3. The gravitational force on the moon is weaker than on Earth.
4. The textbook has a stronger attraction to Earth.

Physical Science 8 B - Unit 4, Lesson 2: Gravitational Force Quick Check Answers
If the planets are similar in radius, the weight of an object would depend on the mass of the planet. Therefore, the planet with the highest mass would have the greatest gravitational force.
To determine which planet an object would weigh the most, we need to consider the gravitational force acting on the object. The gravitational force depends on two factors: the mass of the object and the mass of the planet.
Assuming that the planets have similar radii, the mass of the planets can be considered proportional to their volumes. Since the volume of a sphere is proportional to the cube of its radius, we can assume that the mass of the planets is proportional to the cube of their radii.
Comparing the options given, we need to determine which planet's radius is the largest. Let's analyze each option:
- Planet X: We don't have any information about its radius, so we cannot determine the mass of the planet.
- Planet Z: We don't have any information about its radius, so we cannot determine the mass of the planet.
- Planet W: We don't have any information about its radius, so we cannot determine the mass of the planet.
- Planet Y: We don't have any information about its radius, so we cannot determine the mass of the planet.
Based on the given information, we cannot determine which planet an object would weigh the most. Additional information, such as the radius or mass of each planet, is needed to make a conclusive determination.
