Chapter 4, Problem 1FTD
Distinguish the Aristotelian and Galilean/New Ionian views of the natural stale of motion.
Expert Solution & Answer
To determine
To distinguish: The views of Aristotelian, Galilean, and Newtonian on natural states of motion.
Answer to Problem 1FTD
The difference of views of Aristotelian, Galilean, and Newtonian on natural states of motion is explained.
Explanation of Solution
The view of Aristotle on natural state of motion:
- As per Aristotle, the motion needs a cause. That is,
- A push or pull is required to keep the object in motion.
The view of Galileo on natural states of motion:
- No push or pull is needed to keep an object in motion.
The views of Newton on natural states of motion:
- As per Newton, the force is the push or pull needed to change the motion of an object.
- He formulated quantitative law to explain the change of motion.
