Physics as taught in high school would say that work is a scalar quantity.
More sophisticated forms of physics would say that work done is a Quaternion, both a scalar and a vector.
Work is both
- w= [0,F][0,D]=[ 0 - F.D, 0 + 0 + FxD] = [-F.D, FxD] = -F.D + FxD.
-F.D = -FDcos(FD) is scalar work out, and
- w= FxD= FDsin(FD) a vector called Torque.

A vector quantity has direction a scalar quantity does not true or false?
True, a vector quantity has direction, and a scalar quantity does not.
Is electric potential energy a vector or scalar quantity?
Electrical Potential Energy is a scalar or real number. Ep = zc e2 /4pi r.Total Energy is a Quaternion, the sum of the real or potential energy and the vector energy, Ev= mcV;E = Es + Ev = zc e2 /4pi r + mcV where Ev = mcV and V is the vector velocity.
Is extension a scalar or vector quantity?
Scalar quantity has only magnitude , but no direction while vector quantity has both magnitude and direction.You can understand it by comparing speed and velocity.Velocity has magnitude of speed in a particular direction (or say displacement/time take) while speed only defines the rate of distance covered (no direction). If you are still unable to get your answer for your question then please, elaborate or give some description of extension. -Ajlan Wasfi Khan
Is bytes a vector or a scalar quantity?
A byte is 8 bits. They can represent all of the ASCII characters and any value between 0 and 255. It could be both. It just represents a value.
What is another name for kinetic energy?
Another name for heat energy is Thermal energy.
Is work done a scalar or a vector quantity?
Work done is the amount of energy transferred by a force acting through a distance. It is a scalar quantity.
Electric potenial scalar or vector why?
Electric potential is a scalar quantity since work done and charge are scalars
Is the work vector quantity or scalar quantity?
Work is a scalar quantity.
Why work is scalar but product of two vector?
The product of two vectors can be done in two different ways. The result of one way is another vector. The result of the other way is a scalar ... that's why that method is called the "scalar product". The way it's done is (magnitude of one vector) times (magnitude of the other vector) times (cosine of the angle between them).
How is the direction of the vectors involved in the definition of work?
A definition of work W: W = ⌠F∙dsWhere F is a force vector that is dot-multiplying (scalar product) the differentialdisplacement vector dS. The result is the work W, a scalar, done by the force thatproduced the displacement. But notice that the scalar product of both vectors willonly consider the force component that is collinear with the displacement vector.
Is work vector or scaler quantity?
Work is a scalar.
Is the number of leaves on a tree scalar or vector?
scalar lol
What is a scalar times a vector?
A scalar times a vector is a vector.
Is inertia is a scalar or vector?
vector
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
Is power is a vector quantity?
No, power is not a vector quantity. It is a scalar quantity because it only has magnitude, not direction. Power is defined as the rate at which work is done or energy is transferred.
Is work and energy scalar or vector quantities explain?
It is scalar. This simply means that - unlike vector quantities - energy is not defined in a particular direction.
