Work is defined as a dot product of force and displacement. There are two types of physical quantities. One is scalar quantity(which has only magnitude with no specific direction) and the other is a vector quantity(which has a magnitude with a particular direction). Energy is a scalar. So work is also scalar.Click to see full answer. Beside this, why is work considered a scalar quantity?In other words, work done due to displacement caused by a force is a scalar quantity. The dot product of vector quantities is always scalar which means it is has only magnitude and no direction.One may also ask, why work is a scalar quantity Quora? Any one-dimensional quantity which only gives a measurement of its magnitude, irrespective of any specific direction, is a scalar quantity. Work is said to be done when a force F acts on a body at an angle Φ, thus displacing the body over a length s. Then, which type of quantity is work? Work done is the dot product of force and displacement. Since the dot product of two quantities is always a scalar, therefore, work is a scalar physical quantity.Does work have direction?If the displacement is in the direction of the force, then work is positive. If the displacement is in the opposite direction of the force, then work is negative. So, the work done depends on direction. So work should be a vector quantity.
