Question

Work, is it a scalar quantity or vector quantity ?

Answer 1

In other words, work done due to displacement caused by a force is ascalar quantity. The dot product ofvector quantities is always scalarwhich means it is has only magnitude and no direction.

Answer 2

Answer:

$\huge{\underline{\underline{\sf{\pink{Answer}}}}}$

✦A scalar or scalar quantity in physics is one that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude, possibly a sign, and no other characteristics.

✦Vector, in physics is a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude.

Work is dot product of vectors force and displacement , and dot products are scalar. Therefore work is an scalar quantity.

Work is dot product of vectors force and displacement , and dot products are scalar. Therefore work is an scalar quantity. Another way of telling this is work has only magnitude and no direction, so it is a scalar
