how work done is scalar quantity, while work done is product of force and displacement and they both have direction and both are vector quantities. so then why work done is scalar quantity. Please solve this confusion.

If we can recall the lesson about vector. Work is the dot product of two vector quantities force and displacement. The dot product always gives a scalar quantity. Therefore work is also a scalar quantity.

If we push any object and there is no movement, which means displacement is zero, in that case work done is zero. But what will be transfer of energy in this case?

Outstanding Question! 👏👏👏 Well, brother work is always equal to energy. OR. You can say that work and enrgy are the two sides of same coins. Now, when you exert force on an object and it doesn't move. So work done is zero. What about energy? The answer is simple... Transfer of energy is also zero. But this is purely an ideal case. (In real life, when you exert some sort of force on a body, you tranafer some sort of energy to that object. For example, Heat Energy. But it is so small amount that you can't detect it or you can say that it is negligible.) I hope it will clear the concept... Thanks

I have one doubt sir,without force we can't do work. So,how force is getting different from energy.

Force is a push or pull. Force tends to produce motion. Force tends to stop a moving object. For example, when you throw a ball, motion produces in the ball. So exert force. Energy is the ability of an object/person to do some sort of work. For example, when you throw a ball you exert force due to which ball covers some distance. So you have energy to throw a ball. Force is a vector quantity. Energy is a scalar quantity. Thanks!!! 😊😊😊😊 Force is a vector quantity.

6:16 sir when force and displacement are in different direction work done need not be equal to zero When force and displacement are perpendicular to each other then work done is zero But your teaching is amazing keep it up

@archiesaludes1987

During walking the negative work done by external frictional forces is small, the negative external work done by the muscular force during each step practically equals the external positive work done.
