scalar measurements differ from vector measurements in that scalar measurements have no directionality.
Example:
If a car travels in a circle with a circumference of 25m it will have travelled:
distance (scalar): 25 m
displacement (vector): 0m
Scalar quantities are physical quantities that have only magnitude and no direction. Examples include mass, temperature, speed, and volume. These quantities are described fully by their magnitude alone.
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.
Scalar
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.

vector
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.
