Scalar
No Direction
Scalars have magnitude but no direction, unlike vectors which have both.
Temperature, being scalar, does not require directional information.
Physical Properties
In physics, scalar quantities often describe physical properties that are not directional.
The energy in a scalar form just states the amount, not where it's going.
Scalar Operations
When used in operations like multiplication, scalars can change the size of another quantity.
Multiplying a velocity vector by a scalar changes its speed but not direction.
