Question
Chapter 5, Problem 1RQ
To determine
The name of the Aristotelean natural motion.
Expert Solution & Answer
Answer to Problem 1RQ
The name of the Aristotelean natural motion is force of gravity.
Explanation of Solution
According to Aristotle model of universe, earth is situated in the centre of the planetary system.
Since the Earth is situated in the centre of the planetary system, the substances in the earth fall towards the centre of the earth. These motions are known as natural motions.
When an external force is applied to an object, the object will start moving. Also the object will stop eventually, when the external force is zero. This motion is known as violent motion.
Similarly, Aristotle proposed that the earth and water displaced by natural motion; they will come to their place naturally.
This natural motion is also explained by Galileo and Newton for different situation. And they named this force as force of gravity. Thus, due to gravitational force, objects are falling towards the centre of earth. Therefore, the natural force can be regarded as the gravitational force in modern day terms.

1. are the twins still the exact same age? If not which one is the older and by how much ?
In the classic 1913 science-fiction novel At the Earth’s Core, by Edgar Rice Burroughs, explorers discover that the earth is a hollow sphere and that an entire civilization lives on the inside of the sphere. Would it be possible to stand and walk on the inner surface of a hollow, nonrotating planet?

There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period.
