Question

we know....W= F×S but Force and displacement both are vector quantities So....Why work is said to be a scalar quantity ?

Note: (Should not be copied grom any search engines...)

Answer 1

we know that vector quantity has magnitude and directions both but scalar quantity has only magnitude, it doesn't have direction.

we know that

W=F×S


we know that if we apply force on an object it should be displace .If object will displace , then it is said to be work done we know that some work is done on object and but don't know in which direction the work is done, I. e.,work do not have direction , so work is scalar quantity.




hope this helps you. ......
