Introduction
We will learn about What were the Aristotle's and Galileo's views regarding uniform motion.
Pre-Requisites:
Basic knowledge about force and moving body.
Activity:
Try to push a ball forward in water and observe is it difficult to move.
Real Life Question:
Why does a moving body stops after some time if we don't apply a force on it?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Viscous Force | Opposing force caused by the fluids to resist any kind of motion. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| A ball | Push a ball and find why it stops after moving some distance. |
Real life uses :
Study of mechanics becomes easier.
Places to visit :

Practical examples around us
| Examples | Explainations |
|---|---|
| Every thing in motion | Everything thing around us in motion follows the principle that, for uniform motion we need to apply a constant force. |
What you learn in Theory:
Aristotle said that," External force is required to keep body in motion."
What you learn in Practice:
Aristotle's argument is valid only for the surfaces where opposing forces exist. He did not tell about the frictionless surfaces, what Galileo corrected in his argument.
