Not at all. Scalar are numerical quantities without direction (for example time) where as vectors are numerical
quantities with direction (for example gravitational force downward)
A scalar times a vector is a vector.
vector
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
A vector is characterized by having not only a magnitude, but a direction. If a direction is not relevant, the quantity is called a scalar.
Mass is a scalar value. Scalar refers to the magnitude of the object. Vector refers to the direction. If an object is moving, it's mass is scalar and its velocity is vectorial because the velocity has a magnitude (how fast) and a direction. Hope this helps. Search Scalar and vector for the true scientific definitions.
The magnitude alone of a vector quantity is often referred to as the scalar component of the vector. This represents the size or length of the vector without considering its direction.
Scalar
The arrow over letters is typically referred to as a "vector" notation in mathematics and physics. It indicates that the letter represents a vector quantity, which has both magnitude and direction. For example, a vector denoted by (\vec{v}) indicates a vector named "v." This notation helps distinguish vectors from scalar quantities, which are represented by regular letters without arrows.
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.
An earthquake is neither a scalar nor a vector. It is an event.
