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.
What else can I help you with?
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.
The speed and direction of a moving object is called?
velocityYou mean, Velocity.. Velocity is the rate of change of displacement (position). It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed, a quantity that is measured in meters per second (m/s or ms−1) when using the SI (metric) system.I linked my source.Speed in a specific direction is called velocity.speed is a scalar unit whereas velocity is a vector unit.Speed is the rate of change of position. In vector terms, speed is the magnitude of the velocity. (Velocity is speed and direction; speed is the velocity along a given direction.)
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Which is a vector quantity speed or velocity?
Velocity is a vector quantity because it includes both the speed of an object and its direction of motion. Speed is a scalar quantity because it only represents the magnitude of motion without direction.
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.
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.
Is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
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 velocity in a given direction?
Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
Is a vector quantity is always the same as a scalar quantity?
No, a vector quantity and a scalar quantity are different. A vector has both magnitude and direction, while a scalar has only magnitude. Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities.
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 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
What is different between speed and velocity?
Speed is a scalar quantity that refers to how fast an object is moving, whereas velocity is a vector quantity that refers to both the speed and direction of an object's motion. Speed is the magnitude of velocity.
