It's the year 2180 and a human settlement has been created on Titan, one of Saturn's moons, and your family has been invited to live there!
After you arrive, you notice that you suddenly weigh much less than you did on Earth.
Using this information, deduce whether Titan is smaller, larger, or roughly the same size as Earth. Justify your answer.
When you deduce something, or deduce that something is true, you reach that conclusion because of other things that you know to be true.
To justify a decision, action, or idea means to show or prove that it is reasonable or necessary.

Based on the information provided, it can be deduced that Titan is smaller than Earth. The decrease in weight upon arrival suggests a decrease in gravitational pull, which is directly influenced by the mass of the celestial body. Since the weight is less, it can be inferred that Titan has a smaller mass and therefore a smaller size compared to Earth.
Furthermore, the fact that a human settlement has been created on Titan implies that it is capable of sustaining human life. This suggests that the moon must have a surface area and atmosphere that can support a population, which would be more likely if it were smaller than Earth.
In addition, the lower gravity on Titan could also be associated with a smaller size. A smaller celestial body would have less mass and therefore less gravity to hold objects down, resulting in the feeling of reduced weight experienced by the family upon arrival.
As an astronaut exploring distant alien worlds, you have been granted the honour of being the first person to ever step foot on planet Rumina.
You have been told that the gravitational force exerted by this planet on objects is half the strength of Earth's gravitational force.
Compare your expected weight and mass on Rumina to your weight and mass on Earth.
When you compare things, you consider them and discover the differences or similarities between them.
Write at least 3 sentences in your response.
Based on the given information, it can be inferred that if the gravitational force on planet Rumina is half the strength of Earth's gravitational force, then my weight on Rumina would also be half of my weight on Earth. This means that I would weigh less on Rumina compared to my weight on Earth.
However, it is important to note that my mass would remain the same regardless of the gravitational force. Mass is a measure of the amount of matter in an object and is independent of gravity. Therefore, my mass on Rumina would be the same as my mass on Earth, despite the difference in weight.
