There is no such thing as scalar and vector forces. However, there are scalar and vector QUANTITIES, and force is a vector quantity, as all forces have direction and magnitude. Scalar quantities, on the other hand, have only magnitude and no direction.

Scalar forces have only magnitude, such as pressure and temperature. Vector forces have both magnitude and direction, such as force and velocity. Scalars are represented by single values, while vectors are represented by quantities with both magnitude and direction.
No, stress is not a vector quantity. It is a scalar quantity that represents the internal forces within a material.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
A scalar is a single quantity that is represented by just a magnitude, such as temperature or speed. A vector is a quantity that has both magnitude and direction, like force or velocity. Scalars can be thought of as a subset of vectors with zero direction component.
