Introduction
Newton formulated his first law on the basis of the Galileo's ideas about motion.
Pre-Requisites:
Basic knowledge about Galileo's law of Inertia.
Activity:
take an empty glass, put a small piece of card board on that ad a coin over the card board. hit the card board speedily and see what happens to the coin.
Real Life Question:
Why we are able to walk on the road?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Self Adjusting Force | A type of force which varies with the body parameters. like if the weight of the body is more, reaction force will be more. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| A pile of coins, striker | Hit the pile of coin with the striker and find out why the bottom most coin moves out without disturbing the whole pile. |
Real life uses :
Walking, driving vehicle, etc
Places to visit :
Your home, physics lab or anywhere you want to go.
Practical examples around us
| Examples | Explainations |
|---|---|
| Bus | We feel a backward jerk in the bus when it suddenly starts moving. |
What you learn in Theory:
Every body continues to be in its state of rest or of uniform motion in a straight line unless compelled by some external force to act otherwise.
What you learn in Practice:
It is the inertia which opposes the change in the state of motion of the body. In other words an external force is required to move body either from rest or to stop from its state of uniform motion.
