In physics, "vector" usually means that a direction is relevant. If you just have a number, as in "number of moles", then a direction is NOT relevant.

A scalar times a vector is a vector.

A scalar is just a number. A vector is a row or column of numbers. For example: 6 is a scalar while (1, 0, 23.5) is a vector.

Since you can represent that with a single number, it isn't a vector - just a scalar.

(vector) times (vector) produces either a vector or a scalar, depending on whether the vector product or scalar product is performed. (vector) times (scalar) produces a new vector.

Position is Vector, not scalar.

A Vector. A scalar times a vector is a 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.

The product of scalar and vector quantity is scalar.

Yes, the magnitude of a vector is a scalar.

A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180Â°.

A scalar quantity added to a vector quantity is a complex quantity. An example is a complex number z = a + ib, a is the scalar and ib is the vector quantity.If the vector quantity is 3 dimensional, ib + jc + kd, then the scalar and vector forms a quaternion quantity.
