Newton's law of motion


Motion- 

a particle is said to be in motion if it's position is changing with time



Newton's first law of motion-

                        According to first law of motion a body or particle will remain in its original position unless any external forces act over it

Force-   

         It is a factor which have tendency to make change in position of particle

Newton's second law of motion- 

   According to it change in momentum is directly proportional to the force



Newton's third law of motion

       According to it every action have equal and opposite reaction

FUNDAMENTAL QUANTITY -- Those quantities which cnnot be derived from other quantities are called fundamental quantities. Eg. Mass, length and time. A base unit (also referred to as a fundamental unit) is a unit adopted for measurement of a base quantity

SCIENCE-                प्रकृति के क्रमबद्ध अध्ययन से अर्जित प्रयोगों से प्रमाणित प्राप्त सुव्यवस्थित ज्ञान को ही विज्ञान कहते हैं। यहां क्रमबद्ध से तात्पर्य है :एक प्रयोग करने के बाद जो निष्कर्ष निकलता है उस निष्कर्ष का किसी अन्य में प्रयोग करना अर्थात एक के बाद दूसरा दूसरे के बाद तीसरा प्रयोग करना उसका अध्ययन करना है। Science is a word of Latin language that is made by "scientia"  And it's mean is "TO  KNOW" PHYSICS-                 it is made by Greek word "FUSIS"  That mean  "nature" फिजिक्स विज्ञान की वह शाखा है जिसमें सामान्य तौर पर यूनिवर्स में हो रहे प्राकृतिक घटनाओं का विश्लेषण किया जाता है और इन घटनाओं को समझा जाता है It is also known as science of measure because in it scientists try to calculate maximum possible pure value
