𝐖𝐡𝐨𝐥𝐞 𝐂𝐡𝐚𝐩𝐭𝐞𝐫 𝐬𝐡𝐨𝐫𝐭 𝐧𝐨𝐭𝐞 : Force: Force is any interaction which when unopposed produces acceleration in an object. • It's SI unit is Newton denoted by capital N • It's fundamental unit is Kgm/s^2(force = mass x acceleration therefore Newton = kg× m/s^2 ) • It's CGS unit is Dyne 1N = 10^5 Dyne • Acceleration is produced due to force. Force is the reason behind acceleration. • Force is of two type: 𝐈. 𝐁𝐚𝐥𝐚𝐧𝐜𝐞𝐝 𝐅𝐨𝐫𝐜𝐞 𝐈𝐈. 𝐔𝐧𝐛𝐚𝐥𝐚𝐧𝐜𝐞𝐝 𝐅𝐨𝐫𝐜𝐞 i. Balanced force : set of forces which produce zero acceleration is called balanced force. In points : • Net force acting on the body is zero. • Net acceleration is also zero. • It is the reason behind maintaing the previous inertia of the body i.e Rest, motion or direction. • The body is moving according to the previous inertia i.e Rest, motion Or direction. ii. Unbalanced force : the set of forces which produce non zero acceleration is called unbalanced force. In points: • Net force acting on the body is non-zero. • Net acceleration is non-zero. • It is the reason behind changing the previous inertia of the body. • The body is in accelerated motion. 𝐈𝐧𝐞𝐫𝐭𝐢𝐚 : The property of a body to oppose the change in its state i.e rest, motion or direction. • Inertia is directly proportional to the mass of the body. • More the mass, more will be the inertia. 𝐄𝐱 of inertia of 𝐫𝐞𝐬𝐭: i. When a car accelerates abruptly our lower body, which is in contact of car moves forward but our upper body remains in rest due to inertia and we move backward. ii. When the branch of tree is shaken vigorously, the leaves, fruits or flower hanged on the branch fall down. The branch of tree comes in motion due to shaking but the leaves, fruits and flowers remains in rest due to inertia and get detached. 𝐄𝐱 of inertia of 𝐦𝐨𝐭𝐢𝐨𝐧:- i. When the bus stops suddenly, we move forward. ii. Bicycle moves for some distance until frictional force stop it even without peddling. 𝐄𝐱 of inertia of 𝐝𝐢𝐫𝐞𝐜𝐭𝐢𝐨𝐧: i. We found it difficult to change the direction of a bike moving with high speed . This is due to inertia of motion as the bike is moving in the straight direction and opposes to change it's direction. •Galelieo Galilee said that "the body is naturally either in rest or in uniform motion". • An external unbalanced force is required to change the state (rest Or motion) of an object. Then after Isaac Newton gave his three laws of motion : i. Law of inertia ii. Law of mass and acceleration iii. Law of motion #𝟏𝐬𝐭 𝐋𝐀𝐖 :- • It states that, " A body at rest will remain at rest and a body in motion will continue in motion in a straight line with a uniform speed, unless an external unbalanced force is applied on the body " • If a body is moving with constant acceleration then constant force is appliyng on the body (continuously) . # 𝐌𝐨𝐦𝐞𝐧𝐭𝐮𝐦 :- • It is the quantity of motion contained by a body. • It is the product of mass of a body and it's velocity. • It is denoted by small (p). • It's SI unit is Kgm/s or Kgms^-1. • It's formula :- Momentum = mass x velocity p = mv • Change in momentum is denoted by ∆p (pronounciation: delta p ∆ is used to denote change ). #𝟐𝐧𝐝 𝐋𝐀𝐖 :- • It states that, " Rate of change in momentum is directly proportional to the external unbalanced force applied on the body." • Acceleration produced in a body is directly proportional to the force acting on it and inversely proportional to the mass of the body. • Rate of change in momentum is denoted by ∆ p. • Therefore, Force ∝ Change in momentum / Time. F ∝ ∆p / ∆ t. # 𝐃𝐞𝐫𝐢𝐯𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐟𝐨𝐫𝐦𝐮𝐥𝐚 𝐅= 𝐦𝐚 ( 𝐅𝐨𝐫𝐜𝐞 = 𝐦𝐚𝐬𝐬 × 𝐚𝐜𝐜𝐞𝐥𝐞𝐫𝐚𝐭𝐢𝐨𝐧) • F = ma is a derived formula. Derivation :- F ∝ ∆p / ∆t F ∝ mv - mu /t (mv = mass × final velocity , mu = mass x initial velocity). F ∝ m( v-u) /t F ∝ ma (a = v-u/t ) F = kma (where k is constant..) The value of k in SI unit is 1, so the above equation becomes:- F = ma #𝐍𝐨𝐭𝐞: To remove propotionality we have to put a constant, like we done : F ∝ ma F = kma (k is constant). #𝟑𝐫𝐝 𝐋𝐀𝐖 • It states that, " Whenever one body exerts force on another body, the second body exerts equal and opposite force on the first body. • In other words, " To every action their is an equal and opposite reaction". • Ex:- we walk (force on ground, action ; force on foot reaction), we swim etc.. # 𝐀𝐜𝐭𝐢𝐨𝐧 𝐑𝐞𝐚𝐜𝐭𝐢𝐨𝐧 𝐏𝐚𝐢𝐫 • Acts on two different bodies • Action-reaction pair has force of same nature. • Forces are collinear • No delay

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.

Also known as retardation?

Hi

Anyone in August ?? 👍👍

Watching now, teacher will start this chapter after summer vacation

[@Kamaqua.]

Bro sameee

I recommend to complete the chapter

[@discipline-u9x]

1:41:50 constant velocity

[@JEE--2028_STUDENT]

1:23:38 , Because the brakes applied which is negative acceleration or retardation . Thankyou ❤

[@Fahad_chalkoo]

Right...❤

[@kushagragupta5705]

Ist time I see a video in which I am not tired... Thanks PW for understanding me this chapter.. 😊

[@Winter__bear]

1:23:17 The force is negative means it is applying in the opposite direction

[@DhrubajyotiBora-sc9tw]

Friction?

[@dhairyasongra0910]

1:23:32 The subtraction/minus sign is there to denote the negative acceleration or retardation due to the breaking force applied on the ca

[@riyavishwakarma9886]

Thx bro were confused here 😊

no problem bro @@riyavishwakarma9886

We can also say that the - sign represents the force exterted by the brakes which is 7500N but as it is in opp velocity in relation to the body it is denoted as - if the movement of body is denoted as - then the force exterted by breaks will be in positive the - represents the direction of force here

[@AyushKondekar]

1:23:16 force is negative means that the force is applying in the opposite direction to the motion of the motor car which is applied by brakes in opposite direction

[@Sishlu]

1:23:35 because the negative sign only show that the velocity of object is decreasing which we denote it by retardation.

[@ishansinha2614]

And also it's direction

[@avancubes]

Retardation

[@Deepak97684-m]

@@ishansinha2614 yes

[@irfankathat7920]

What nonsense negative sign denotes the direction is west according to cartesian plane

[@Deepak97684-m]

@@irfankathat7920 here no one said the direction to east lol 😆

Teaching skill of sir is amazing . What a amazing teacher! 👌🏻👌🏻

[@Shalzz-w3o]

Thankyou so much sir 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@daxarathod931]

Amazing explanation by Rakshak Sir hats offf to PW and team!!!

[@CANdYK9._.47K]

1:42:08 yes exactly! Just like how I apply force (efforts) on scoring well on exams... But it has more mass (i.e., difficulty level of question paper) than my force (efforts) that's why my efforts to score well on exams are always invisible cuz no matter how much I try, the exams always have more mass than my efforts.... 😅🥲😢😭 Hope you understand what I'm trying to say...

[@durgeshojha2009]

❤Releatable ❤

[@Triggered_Radhika]

I​@@durgeshojha2009 it is relatable 😂😂😂😊

[@saritabhardwaj1470]

1:23:17 beacuse the body is deacclerating which means the body is coming from final to initial position from which the speed is decreasing ❤

[@ayushmanpandey3050]

Bhai thoda precise me smjha de pls😢

[@Priaaaaah]

Sir the negative sign tells us that the force exerted by the brakes is opposite to the direction of motion of the motorcar👍👍✍️

[@op...gaming4719]

THANKS SIR 👍👍☺️☺️ FOR THIS WONDERFUL EXPLANATION OF THIS CHAPTER 👍👍☺️☺️.

[@viii4-10baibhavdas4]

1:23:45 it came minus because the force is applied on opposite direction

You must be in 10th now huh

[@StudyTime-h5o]

Best teacher of physics in whole India I truly said that ❤❤❤

[@Manya5724]

Minus sign before force indicates that force is applied in opposite direction in which the body is moving(like it is a frictional force stoping the vehicle)

sir maza aata hai physics mai 8th mai hi paadh raha hun baas yaah lagta hah ki app jaase teacher school mai ho na to aasa ho nehi sakta ki phisics mai kisi ka intrest na ban paay PW and you are best thanku

[@Ssyylll0103]

Thank you so much sir ji 🙏 Waited for this session 🔥

Uniform motion as well as rest 😊😊❤❤

[@Bhajananmolras13233]

यदि कोई गेंद किसी तिरछी सतह पर है और आप उसे छोड़ देते हैं तो गुरुत्वाकर्षण उसे ढलान पर लुढ़कने पर मजबूर कर देगा, इसमें जड़ता है और यदि ढलान के नीचे एक समतल क्षेत्र है तो वह चलती रहेगी।

[@santoshramachandran1190]

22:18 uniform motion OR rest ( here acceleration is zero as the force acting on it is zero)

[@Alexanderbhai7]

I am class 10 pass out students still I am studying all chapter of 9 class math and science 😊

[@vaishgupta147]

Why??

[@santoshipatwal1043]

Kitni percentage aayi?

[@ashishpandey6200]

Negative sign of force say the force which exert opposite to the direction of moving body Thai is known as force of friction❤
