Force and Laws of Motion Class 9 I Malayalam I Newton's Third Law of Motion

#lawsofmotionclass9 #class9physics #newton’slawsofmotion
Third Law of Motion
Newton’s 3rd law states that every action has an equal and opposite reaction. Action and reaction forces are equal, opposite and acting on different bodies.
Whenever one body exerts a force on another body, the second body exerts an equal and opposite force to the first body. Or, to every action there is an equal and opposite reaction.
Action and reaction forces are equal and opposite.
Application of Newton’s 3rd Law:
Gun applies force on bullet due to which it moves ahead. By Newton’s 3rd Law, bullet will also apply same force on gun in backward direction. Due to this force, gun moves back. This is called recoil of gun. Gun moves back only by small amount due to its heavy mass.
Hose pipe applies large force on water due to which water moves ahead. By Newton’s 3rd Law water applies the same force on pipe backwards. Due to this force, pipe can move backwards. To stop it, many people need to hold it.
Man pushes the boat backwards and by newton’s 3rd law, boat pushes man forward.
Man pushes water back by applying force. By Newton’s 3rd Law, water applied equal and opposite force on swimmer. Due to this force man moves ahead.

Many have doubts on Newtons law, this video has given well and detailed explaination

madam in case of sailor and boat ,when sailor jumps out of a boat , he exert a backward force of the boat (action)and the boat exert and opposite force on the sailor (reaction)and the sailor jumps forward.

Yes✌🏻✌🏻

Yes

Mam, in the case of gun we pull the recoil at first, then only the bullet come on action. So the pulling of recoil is the action and the bullet is the reaction. Is n't it. If not can you explain

[@Easyphysicswithjesnof]

We apply force on the bullet by the GUN first and as a result bullet will apply the reaction force on the GUN

Mam Presentation super Very useful video

[@Easyphysicswithjesnof]

Thank you for ur feedback 😍

[@vysiamkumargmail.comaneena3982]

Mam can u explain once more..plsss

[@alwindev4832]

Mam could you pls upload a video on how to do the problems on recoil of gun.....Btw your classes are fabulous.....

Why we can't stand on water...is it against newtons 3rd la w

[@Easyphysicswithjesnof]

When u stand on water there are two forces acting on you. One is gravitational force (downwards) and second buoyancy (upwards). Density of our body is more than density of water. That’s why we sink in water.

@@Easyphysicswithjesnof Thanks But every action has equal and opposite reaction...how is it possible If a cart is pushed while on ice,it can't move...is this violate 3rd law

[@parkrose1950]

Can you explain why forces always occur in pairs??(please ma'am)

[@Easyphysicswithjesnof]

Forces are always pushes or pulls between two objects ,so they always occur in pairs. According to Newton's third law, for every action force there is an equal (in size) and opposite (in direction) reaction force
