A unit vector.
A physical quantity that is specified by both magnitude and direction is a vector by definition.
scalar
That's called a "scalar" quantity. Examples include temperature, speed, and energy.
the quantities which have both magnitude and direction are called vector quantities
The quantities that describes about only magnitude is called SCALAR quantity
A quantity involving direction and magnitude is called physically vector A quantity involving direction and magnitude is called physically vector
A physical quantity that is specified by both magnitude and direction is a vector by definition.
The "size" of a vector quantity - such as a force - is often called a MAGNITUDE.
scalar
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.
Because it only has magnitude and not direction.
That's called a "scalar" quantity. Examples include temperature, speed, and energy.

Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
Shortest distance is called displacement . displacement =average velocity / average time . It is a vector quantity both has magnitude and direction.But,distance is a scalar quantity having only magnitude.
