Newton's Second Law of Motion (Force - 6) in Hindi for Class 9 Science

In this Science (Physics) video in Hindi for Class 9 we explained Newton's second law of motion and derived the relationship among applied force, mass of the body and acceleration created due to that force. It is a topic from chapter 9 - ' Force and Laws of Motion' from NCERT.
The second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.
Further, we get force is equal to the product of the mass of the object and the acceleration produced by that force. F = ma.
The S.I. unit of force is newton or kg m s^(-2).
1 newton is the force when acted on 1 kg mass produces an acceleration of 1 m s^(-2).

Sir , sabhi teacher kahate hai ki body per force apply kroge to. Acceleration hoga but my question is that agar force ka use velocity ko constant rakhne ma use ho to according to 2nd law of motion, F=ma then calculate karne per force=0 iska matlab force zero apply ho raha h 😂 but how plzzzzz....

Sir, what is difference between net force and simple force?

[@ibetudkmahnameb4114]

Net force wo resultant force hota hai matlab jo force opposite direction me lag rhe hai unko minus karne ke baad jo ata hai vo/total force . Aur simply force matlab jo force lag rha hai, nali total force. Ex: agar tum khade ho aur tumhe 1 baccha haat pakad kr kheeche (let's say 5N ke force se) aur dusra baccha dusra haath pakad kar keeche(let's say 10N ke force se)
So, net force =10N-5N= 5N

In the sense of producing acceleration, balanced force is the same as zero force.
