why work is considered a scalar quantity as force and displacement are vector quantity
Asked by | 24 Nov, 2012, 09:55: PM
answered-by-expert Expert Answer
Work is a scalar quantity because work is a dot product of two vectors i.e. force and displacement and dot product is a scalar quantity. We hope this clarifies your doubt.
without mentioning the direction we can understand work or value of work is sufficient to understand its effect.
