Why is velocity a vector quantity and speed is a scalar quantity?

Because it is:
* A property of physical objects
* Something that can be measured (or calculated from other quantities)
Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.

Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Why is speed classified as a scalar quantity and velocity classified as a vector quantity?
Speed is the rate of which an object is moving altogether and is a scalar quantity and thus only requires a magnitude and is found by the use of the formula speed=distance/time SI unit = m.s-1 Velocity is the rate of which a object is moving in a given direction, so is vector quantity and both a magnitude and direction are required found by the formula velocity=displacement/time SI unit = m.s-2
What describes how fast an object is moving and in what dirrection?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
What is an example of the difference between speed and velocity?
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Is speed a scalar quantity or vector quantity?
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Why is speed classifies as a scalar quantity and velocity classified as a vector quantity?
Speed = distance/ time Velocity = displacement / time distance is scalar and displacement is vector
Is average speed of a vehicle a vector or scalar quantity?
In physics:If you talk about speed, that refers to a scalar quantity.If you talk about velocity, that refers to a vector quantity.
Is instantaneous velocity a vector quantity?
YES!!! Because velocity is speed in a given direction(vector). e.g 30 mph is a scalar quantity, but '30 mph in a northerly direction' is a vector quantity, because it has direction.
Is km s a vector quantity?
km/s can be either a vector or a scalar quantity. It is a unit of speed, which is scalar, but if this speed is in a specific direction, thereby becoming velocity, it is vector.
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
Is speed a scalar quantity?
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
Speed is to scalar quantity whereas velocity is to?
... a vector quantity. Speed is a scalar, meaning only the magnitude (a number) is used. If the direction of a movement is of interest, you use the word "velocity", instead, to describe the vector. A vector has both a magnitude and a direction.
Velocity is a measure of both an object's speed and its what?
Direction. Velocity is a vector quantity. Vectors have a scalar size and a vector direction.
