A vector is a directed segment representing a quantity that has both magnitude and direction.
<Hope this helped!>
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
Vectors need both magnitude and direction.
A quantity involving direction and magnitude is called physically vector A quantity involving direction and magnitude is called physically vector
for a vector quantity it must have both magnitude and direction and since it has both magnitude and direction it is therefore considered a vector
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
A force is a vector quantity because it has both magnitude and direction.
Distance is a sclar quantity. A scalar quantity is a magnitude only. A vector has magnitude and direction. Distance AND direction is a vector quantity.

A Scalar Quantity is a physical quantity which has only magnitude and no direction associated with it . For eg,mass is a scalar quantity beause it has only magnitude (say 5 kg)but has no direction in which the magnitude acts towards.on the other hand a physical quantity which has both magnitude and direction is called a vector quantity.like weight is a vector quantity because it has magnitude along with direction(i.e. it always acts in the downward direction.
A physical quantity that is specified by both magnitude and direction is a vector by definition.
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
A vector is described by magnitude and direction (a scalar has only magnitude).
Velocity.
scalar
speed has only magnitude but no direction associate to it, if you consider velocity it consists of magnitude along with the direction. Hence speed is considered as a scalar quantity
