a vector
Vectors
A vector quantity has both size (magnitude) and direction involved but a scalar quantity only has size involved and not direction.
Speed is a measure of how fast an object is going. This is a scalar quantity, which means it only gives magnitude (size) information. Velocity is a vector quantity, which is very similar to speed, but it also includes direction information.Example:Speed of car = 60 km/hVelocity of car = 60 km/h in a Northwesterly direction
a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
To measure, or measuring is the use of units to find a size of quantity
Velocity is a vector.Its magnitude is called 'speed'.
A vector quantity has both size (magnitude) and direction involved but a scalar quantity only has size involved and not direction.
scalar quantity has only magnitude whereas vector quantity has magnitude as well as direction
A vector is a mathematical quantity that has a magnitude (size) as well as a direction.Its magnitude and direction.
A vector is a quantity that has magnitude and direction. It is typically represented by an arrow pointing in a specific direction, with the length of the arrow representing the magnitude of the vector. Vectors are widely used in mathematics and physics to describe quantities such as velocity, force, and displacement.
A scalar is a quantity that is represented by a single numerical value, without any direction. Scalars are used in mathematics, physics, and other fields to represent quantities like temperature, speed, and mass.
... then what is the question?
A scalar quantity is a physical measure of size--or extent--,while, on the other hand, a vector quantity is a physical measurement of size--or extent--AND direction. A shape has size--or extent--but does not have direction; and I would, therefore, classify it as having a scalar quantity
A vector quantity not only has a size, it also has a direction. Velocity is a vector quantity. "30 mph north" and "30 mph east" are different velocities. "Speed" is a part of velocity ... its size alone, without its direction, so speed is not a vector quantity.
Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
That's called a vector.

In a vector quantity, it is important to specify a direction. In a scalar quantity, it isn't. Vectors (such as force) have a magnitude (size) and a direction (such as North). Scalars have only a magnitude.
