Right😊
1:23:35-The negative sign denotes only the direction. Force is a vector quantity so that that force can be opposing, depending on direction and magnitude. If the implemented force is in the reverse direction to the displacement of the traveling object, then the force will be opposing or negative.
Right bro 👍👍👍

Newton's 4th laws says that every book continuous to be in rest until and unless internal and external exam appears and speed of page turning is directly proportional to the syllabus to be covered and tension in the mind remains constant😊
Whaaaaa jii
Rantsgamer3526's 4th law of motion. 😂
Relatable
If a minus sign comes with the force, it will indicate that the force is acting in a direction opposite to that in which the body is moving ( just as the force of friction acts in a direction opposite to that of moving body)
🎉
Yes correct ✔✅🙂
In S.chand same line is given
Or it can be say as retardation in physics term☺️☺️
Thanks for explaining ❤
22:18 The condition of rest will be achieved because there is no external force acting on the object.

Salute for those who's half yearly exam is tomorrow like me.
i have final exam after 6 hours and now i am revising full physics

but i will surely complete everything in revision and score well
Nah bro 😎 I am watching this video one night before 😅 finall exam 😎
22:18 the body will be at rest or uniform but the answer is :- the body will stay in rest because the force is applied is in both the direction so it will be constant it will neither be accelerated nor be deaccelerated (no change in velocity) in the case of balanced force !
22:18 Both rest as well as uniform motion !
But will be in uniform motion if already in state of motion
If a minus sign comes with the force it will indicate that the force is acting in a direction opposite to that in which the body is moving
Sir you are a best teacher of science
Third Law of Motion , To every action, there is an equal and opposite reaction (Ex- We push a wall) best and easy example 👍👍
29:47 orphan kid crying in the corner💀
40:56 Sir Here The Answer Is 4000N - 5000N = -1000N The Force Can be Negative F=ma so the F is directly proportional to the a so , a is negative then f also negative
Ara woh 40000 hai 4000 nahi
22:15
If the previous state of the object was rest then after applying balanced force it will stay at rest only.
However, if the previous state of the object was uniform motion then after applying balanced force it will stay in uniform motion only.
1:23:17 The force is negative means it is applying in the opposite direction
Friction?
1:23:21 Force = -7500 bcoz jo force hai vo
cartesian plane ke hisab se force west direction mei lag rhi hai or motion mei +/- bass direction batane keliye use kiya jaata hai
Hii
Sir papa laye lati
Lati ka mass = 300g
Hits me with intial velocity
=10m/s
Final velocity =0
Time = 1s me hua sab kuch
V=u+at
0=10+a
a=10 m/s²
F=ma
F=300×10
F=3000N
Hence, The lord lati hits me with 3000N force 😂
Therefore I am in hospital
😂
😂😂😂😢😊😅😅😅😅
30:13
1:23:23 because force is applied in the opposite direction to the intial velocity of the motorcar

To increase the time of change in momentum cricketers move their hand back while taking a catch. As force is inversely proportional to time therefore more time taken for change in momentum results in lesser impact of ball on his hand which avoids injury.
1:23:25 Force is negative because it is applied in opposite direction by the brakes

Because the brakes applied which is negative acceleration or retardation .
Thankyou ❤
Thankyou sir for clearing all my doubts for motions and Force And laws of motion
1:23:19 if a minus sigb comes with the force it will indicate that the force is acting in opposite direction to that in which the body is moving
Ye retarding force hai matlab speed kam hoti jati hai aur friction force ( oppose the motion) opposite direction me lagta hai jiske Karen force minus me ho jata hai
Yes correct correct very correct.👏💯
1:23:12 the answer is in minus because the force applied on the motorcar is in the opposite direction(brakes)
Pata hai
No due to the retardation whenever the brakes are applied the acceleration gets minus due to the opposite direction
Who watch this video after ten exam
Mai bhai
1:23:22. Sir as force is a vector quantity, answer is negative.
1:23:32
The subtraction/minus sign is there to denote the negative acceleration or retardation due to the breaking force applied on the car.
Negative acceleration is the brake applied
@@laksh2367no it is retardation
@@laksh2367 can we say due to frictional force there is minus ??

22:32 because both force are applied in opposite directions and both the force are same so they will cancel each other and state of that object will be rest.

@@jitendrkushwa27 pass ho gya bhai 😎
1:23:38 because it should be opposed by frictional force which is in opposite direction..
no because it is in negative retardation

Cartesian
Auto correct ho gaya honga
1:23:31 Sir since brake is applied the force applied to stop is also acting backwards, and anything applied backwards is negative. Therefore the force in answer is negative.
Good
Right answer

Kitna must padate h sir salute for KOP SIR [KING OF PHYSICS]
22:01 sir vo is bat pe depend karti hai ki object pehle rest pe tha ya motion me tha
Agar rest pe hoga to rest hi degi or motion ( uniform or non uniform) me hogi to objet motion me hi rahega
Non uniform motion likhana sahi nhi hai 😑😑
@@TargetYt-hq6go to bhai ek bar khud hi soch.. na hi tereko na hi mereko balki kisi ko nahi pata object uniformly chal raha hai ya non uniformly . Kul milake bat yahi hai ki agar net force hi 0 hai to object me to koi force act hi nahi karegi
1:23:26, The magnitude of forces is negative it means that :
Force is acting in the opposite direction of acceleration. Thank you sir🥰🥰🥰🥰
It's deceleration or retardation because of acceleration happen in opposite side of mass of body...
Nice
The magnitude of force is negative because there is retardation and force is acting opposite to the motion of the car.
It also shows that force is a vector quantity
According to third law, If force are exerted on same side equally. It means when we push bottle from our hand then bottle should exert equal force on hand then the net force should be zero then why bottle moved
Not then why that's why hoga
1:23:30 - > Because Force Is Applied In Opposite Direction
Also known as retardation?

Last month when my halfyearly was so close I came here for revision and to touch up the chapter but this sir gave so many motivations in a darauni way that I came here in the first day after examination. So that I can complete everything on time ❤️ love you sir
Okk hjii
force is any interaction that will change the motion of the object .
sir namaste interaction means push or pull
1:23:38 minus sign is becoz of opposite force acting on the moving body to make it stop

Sir like u said that inertia is the name of newton's first law of motion but if we look closely with taking some eg like:A tree is shaken vigorously and leaves are detached from the tree so this is the eg of inertia of rest but its not the same as the newton's first t law , 'the tree is shaken vigorously' is the first law eg not the leaves which have detached.
