Why work is scalar quantity where as force and displacement are vector quantity?

Work is the product of a force a
nd a displacement. Both of those are vectors.
There are two ways to multiply vectors. One of them produces another vector,
the other produces a scalar. The calculation for 'work' uses the scalar product.
The procedure is:
(magnitude of one vector) times (magnitude of the other vector) times (cosine of the angle between them).
Answer2:
Work is a scalar because Physics has a major defect in defining energy as a scalar.
Nature defines energy as a Quaternion, the sum of a scalar and a vector.
Work is a Quaternion, W = FD= -F.D + FxD , -F.D is a scalar and FxD is a vector.
Physics defines Work as -FDcos(FD) and defines FxD = FDsin(FD) as Torque.
When Physics understands Nature and Quaternions, then both F.D and FXD will both be recognized as energy, scalar energy and vector energy.

The main difference between a scalar and a vector quantity is?
A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.
Is centre of gravity a vector quantity or scalar quantity?
It's a 0th order tensor, also known as a scalar.
How torque is vector and work is scalar quantity?
Torque is got by the cross product of two vectors namely force vector and perpendicular radius vector Tau (torque) = r X F But work is got by the scalar product of force vector and displacement vector Hence W = F . S
Which is a scalar quantity a. displacement b. distance c. force d. acceleration?
b. distance is a scalar quantity.
Why is force not a scaler quantity?
A force is a vector. That simply means that the direction in which you apply a force is relevant.

Is torque is a scalar or a vector quantity?
Since torque is a force, and as such has a direction, it is a vector.
Which are the scalar quantities?
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.

Is force scalar quantity?
No, it's a vector.
Is forcee a vector or scalar quantity?
Force is a vector. The direction is relevant.

Is thrust scalar or vector?
Thrust is a force and a force is a vector quantity having a magnitude and direction
Is specific gravity a vector or scalar quantity?
Gravity is a force, and forces have magnitude and direction; hence, it is a vector.
Which is a scalar quantity a. displacement b. distance c. force d. acceleration?
b. distance is a scalar quantity.
Why is force not a scaler quantity?
A force is a vector. That simply means that the direction in which you apply a force is relevant.
Why is force a scalar quantity?
Force is not a SCALAR because it always has a DIRECTION, making it a VECTOR. A SCALAR quantity is a one-dimensional physical quantity, i.e. one that can be described by a single real number.
