Laws of Physics- daily life

Laws of physics
Laws of physics is always fascinating me. I do understand that most of the laws of physics are applicable in or daily life too.
Example:
First law of motion:- 
A body in motion will continue in motion and a body at rest will remain at rest unless and until external force is applied to it.

वो कहते हैं ना की ढीठ है. यही ढीठ physics में inertia या law of inertia या first law of motion कहलाता है |
जब तक बाहरी बल या दवाव न डाला जाये एक ढीठ आदमी अगर रुका है तो रुका ही रहेगा या कुछ कर रहा है तो वही करता रहेगा | मतलब की जब तक फाॅर्स ना लगाया जाये एक रुका हुआ वस्तु रुका ही रहेगा और चलता हुआ वस्तु चलता ही रहेगा वो भी सीधी रेखा में |

Summary:-
As per law of inertia a body in motion will continue in motion in a straight line or a body at rest will remain at rest unless and until external force is applied.
जब तक बहुत ज़रूरी ना हो पड़े रहेंगे |

आपका क्या विचार है |
Please let me know about your ideas on this law of inertia, Any comments or suggestion is welcomed.

Oscillations and Vibrations -- My views

I would like to express my idea on what I do think the oscillation and vibration is?

@Phyziks facebook page 

In my opinion, when a particle is moving in a same path again and again we can say that it is oscillating. While vibration is some physical disturbance produced due to oscillation. Consider a particle is vibrating and we are visualizing it in a slow motion. I can feel it is something very much similar to the oscillation. Every oscillating particle has some frequency associated with it and if the range of that frequency lies in the range of audible sound we can listen to that sound. So, is that oscillation a vibration or not.
If I am saying that a vibrating body produces sound wave, am I correct? 
I think a vibration is a microscopic view of oscillation which can be felt clearly. As the frequency of vibration is very higher than oscillation a sound wave can also be heard. What do you think of these two terms.
