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.
Velocity is a vector.Its magnitude is called 'speed'.
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
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
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.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
"Speed" is a scalar; "velocity" is a vector.
Velocity is a vector.Its magnitude is called 'speed'.
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.
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
... 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 vector and speed is a scalar.
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
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.
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 = distance/ time Velocity = displacement / time distance is scalar and displacement is vector
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.
