WORK AND ENERGY ONE SHOT LECTURE WITH ASHU SIR FOR CLASS 9TH | SCIENCE AND FUN 9TH 10TH

[@funzo0001]

Cos-theta concept please

[@HytecGamer]

Sir please

[@AnjanKalita-m8x]

The real and the main formula of work done is W= Fscostheta bcz obj hamesha force jaha par lagaya ha wohi pr move nahi krta in that case same angle form between the applied force and displacement so cos theta is taken for ex agr body force jaha pr apply kiya ha wohi direction me move kra to wo ho jayaga W=fscos-theta W=fscos0degree W=fs Then ye wala +ve work done hoga Aesi he negative work done me minus symbol aayaga agr wos ke cos theta 180 ho jaya I try my best i hope u understand a little ✊

[@1367k]

18:24 yes sir possible hai like if we lift a body to a certain height then displacement is in upward direction and gravitational force is in downward direction

[@_zx10r_love_9]

18:15 Sir, When we pulling a rope into from the well then we apply pull to the rope but the bucket is pushing in opposite direction ⬇️⬆️... 😊

[@Kxu_oo]

[@nalla_insan1717]

Ooo ghanta right

[@bhuvijain1117]

18:20 Example - In a archery when we pull the arrow behind(means force applied at backward direction)but it moves front(means displacement at different direction)

[@sawastiksharma2723]

Because then it applies force in forward direction after getting loaded

[@dheeraj711]

Actually a good example

[@Creativekala_girl]

Yes you are right

[@SAMMYHOOPS]

Isn't the movement (forward)of the string of a bow due to the elastic force, that isn't due to our force

[@YTMANIAOfficial]

18:31 The example of negative work done is when We apply 10N of force on an object but from the opposite direction their is another force applied of 15N thus the Net force is 15 - 10 = 5N In the opposite direction for me where I want to move the object.

[@factnart9760]

18:28 Yes sir this is possible When we apply force on a spring its displacement is on opposite direction.😊

[@pujasahu7039]

18:56 Yes, it is possible that when we apply force in one direction then displacement occurs in opposite direction. Example- we are pulling a bucket from the well. We applied force at downwards but bucket goes upwards means displacement occurs at opposite direction.

[@devil7553]

That's wrong......how can we "pull* downwards?

[@hirdeshkumar8360]

Yes we are not applying force downward

[@anilsinghchouhan1303]

[@Short_vlog_M1]

Correct bro

[@PritpalSingh-qe1zd]

18:33 Negative work occurs when we are applying force in one direction but displacement is opposite of that. in case of Tug of War , if the opponent team is stronger, then even if we pull so hard, the displacement will be in opposite direction.

when force and displacement are in opposite direction😊❤ example 1). When an object is thrown upwards,the force of gravity is in downward direction whereas displacement acts in upward direction. Sir right ❤

Yes, sir the second case of COS THITA is being used in our school. And sir they are even using SIN Thita. And, sir according to class 9 the vector quantity can be positive, negative and zero, but scalar can't be, so what makes work scalar?(*So, is there any property rather than the rule of dot multiplication between two scaler*)

[@ayu4952]

You had point bro

[@Viciousbreezey]

Vector quantity means it has magnitude +direction .It can +,-or 0. Scalar quantity only has magnitude .It can also be +,-or 0. It is not at all important that a scalar quantity always as to be +
