Kinematics is the branch of classical mechanics that describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion.[1][2][3] The term is the English version of A.M. Ampère''s cinématique,[4] which he constructed from the Greek κ?νημα, kinema (movement, motion), derived from κινε?ν, kinein (to move).[5] [6]

The study of kinematics is often referred to as the geometry of motion.[7] (See analytical dynamics for more detail on usage).

To describe motion, kinematics studies the trajectories of points, lines and other geometric objects and their differential properties such as velocity and acceleration. Kinematics is used in astrophysics to describe the motion of celestial bodies and systems, and in mechanical engineering, robotics and biomechanics[8] to describe the motion of systems composed of joined parts (multi-link systems) such as an engine, a robotic arm or the skeleton of the human body.

The study of kinematics can be abstracted into purely mathematical expressions. For instance, rotation can be represented by elements of the unit circle in the complex plane. Other planar algebras are used to represent the shear mapping of classical motion in absolute time and space and to represent the Lorentz transformations of relativistic space and time. By using time as a parameter in geometry, mathematicians have developed a science of kinematic geometry.

The use of geometric transformations, also called rigid transformations, to describe the movement of components of a mechanical system simplifies the derivation of its equations of motion, and is central to dynamic analysis.

Kinematic analysis is the process of measuring the kinematic quantities used to describe motion. In engineering, for instance, kinematic analysis may be used to find the range of movement for a given mechanism, and, working in reverse, kinematic synthesis designs a mechanism for a desired range of motion.[9] In addition, kinematics applies algebraic geometry to the study of the mechanical advantage of a mechanical system, or mechanism.

In simple we say speed=total distance travelled/totat time taken and velocity=shortest distance between initial and final position/total time taken to cover this distance

Speed=total distance travelled/totat time taken Velocity is the rate of change in displacement with respective. velocity=shortest distance between initial and final position/total time taken to cover this distance

speed = scalar (only magnitude) but velocity= vector (magnitude and direction)
speed= distance /time but velocity = displacement/time

    Speed=distance/time while velocity= displacement/time.
    SI unit of both are m/s
    speed is a scalar quantity while displacement is a vector quantity.
    velocity can be positive , zero, or negative while speed can be positive only.

speed is scalar as distance is scalar
velocity is vector as displacement is vector qty

Speed is distance travelled per unit time whereas velocity is displacement per unit time. speed is scalar quantity while velocity is vector quantity.

Speed =distance /time Distance means the actual distance travelled by the body Velocity = displacement/timeDisplacement means the shortest distance travelled the body between initial and final position Speed is a scalar quantity Where as displacement and velocity both are vector So speec can only be positive where as displacement can be positive,zero or negative

Speed=total distance covered/ total time taken..it is scalar quantity (only magnitude) Velocity =distance between initial and final position /time..... It is vector quantity (magnitude and direction)

Speed is a scalar quantity. A scalar quantity has only magnitude. Velocity is a vector quantity. A vector quantity has both magnitude and direction. Speed = Distance / Time taken. Velocity = Displacement / Time taken. Distance is a scalar quantity. Displacement is a vector quantity.

MY FRIEND SPEED IS A SCALAR QUANTITY (WHICH HAS ONLY MAGNITUDE)AND VELOCITY IS A VECTOR QUANTITY(WHICH HAS BOTH MAGNITUDE AND DIRECTION).YOU CAN UNDERSTAND IT CLEARLY IF YOU SEE A EXAMPLE OF BOTH THE QUANTITIES.

Speed is the total distance travelled by a body in per unit time. 
Velocity is the total displacement of a body from the initial position to the final position in per unit time. 
Speed is a scalar quantity whereas velocity is a vector quantity.

speed = distance/time ,  velocity = displacement/time 
 Speed is a scaler quantity while velocity is a vector quantity.
  EX:  If a boy travels a distance from home to playground (200m). Here the displacement and distance both are same(200m). 
         If the boy goes from home to playground and again returns home with constant acceleration then here the distance                would be 400m but the displacement would be 0.
    [ By this we can say that speed and velocity depends on distance and displacement.]

Speed is equal to distance divided by time and velocity is displacement divided by time speed scalar quantity and velocity is vector quantity speed has only magnitude but no direction but velocity of both magnitude and direction

the difference between speed and velocity is    speed = distance / time
                             and
velocity =displacement / time

Speed gas no direction associated with it whereas velocity has direction associated with it. Hence we can say that speed is a scalar quantity whereas velocity is a vector quantity.

Speed is the rate at which an object covers a distance. Velocity not only determines the speed of the object in motion but also the direction of the object in motion.

SPEED IS RELATED TO DISTANCE,WHERE AS VELOCITY IS RELATED TO DISPLACEMENT.THAT IS SPEED DEPENDS ON THE PATH BUT VELOCITY DONT DEPEND ON THE PATH CHOOSEN

Speed is scalar while velocity is vector quantity. Velocity has direction speed doesnt have thats the reason for why speed is always positive while velocity is negative also.
