yaar dekho agr ap school na jatay tu ap ki school memories hoti nahi or tuition hum isliye jatay hai kay jo kam school say milay wo yaad karnay jis insan nay phar na huta hai usnay school or tuition mai hi phar lay na hai or jis nay nai usnay yaha pay bhi nai phar na usny yaha pay bhi time pass hi karna hai
I DONT KNOW WHY I AM SAD AND DEPRESSED MOOD BCAUSE HOW CAN I DO PHYSICS .PHYSICS IS SO HARD WHY I THINK .......... THE BEST TEACHER IS HERE OF PHYSICS SUBJECT ... I FORGET TUSION BECASUE THE WASTAGE OF TIME ...........SIR CAN MAKE A PHYSICS EASY BACAUSE OF EASY LESCTURE NOT A HARD ..........
Sir Great Lecture But You Said That "A Person Doesnt Do Work When He Pick Up A Box" But Actually Work Is Done Because The Force Is Applied And The Box Changed Its Previous Position !
Sir g agr koi banda object ly k khara hota hai to usko bhi physics compensate krti hai potential energy ki sorat my. Work and energy are equivalent forms. Work-Energy Theorem. Basically jb aap khary hen to ap energy my change nahi laa rhy. Jbhi work zero but there is a potential energy partly work form at that point.
Work is defined as a scalar because it depends on the net distance involved, regardless of the direction. If the object winds up where it started, no work is performed because the distance is zero. So work is the transfer of energy from one body to another in which direction is not important. Hence, work is a scalar quantity
You said that''A person doesn't do work when he pick up a box'' but actually work is done because the forces is applied and the box changed its pervious position Read More
The products of Work has no concern whether they are scalar or vector. Basically definition of Scalar is any Quantity that contain Magnitude and Direction, Work do have a Displacement but in most conditions Direction of that Work isn't given, so no direction, it means that its a scalar quantity. I hope you get it. :)
In physics this is a rule that when two vectors will be dot multiplied then scalar will be obtained. Same is the case in work .work is scalar because in work two vectors that are force and displacement are dot multiplied
Hello sir I am confused in the chapter 2 you told me the displacement represent is d but in chapter 6 you told me displacement represent is S I don't understand please anyone explain me this situation
Distance and displacement both can be represented by S as well as d there is no big difference between distance and displacement so for these two we can use anyone of d and S ... For example: as you know that speed and velocity both can be represented by v I hope u understand ..
