Newton established that a force never occurs singly in nature Forces always occur in pairs as a result of mutual interaction between to bodies According to Newton s third law to every action there is always an equal and opposite reaction The force of action and reaction may appear due to actual physical contact of the two bodies or even from a distance The law is applicable whether the bodies are at rest or they are in motion. Read the above passage and answer the following questions
(i) It is difficult to walk on sand or ice Why?
(ii) What does the law imply in day to day life ?

Explanation

(i) On pushing sandy ground th sand slips Therefore force of reaction from sandy ground reduces Similarly friction between our feet and ice is small Thereforc force of reaction from ice is small That is why it is difficult to walk on sand or ice
(ii) In day to day life this law implies that love begets love if you give love to anydody near or far you get love from hin/her in the equal measure/proportion The same is true for ill feelings They also return to you in the same proportion .
