Kinematics

Kinematics is a subfield of physics and a branch of geometry. In physics, kinematics studies the geometrical aspects of motion of physical objects independent of forces that set them in motion. Constr
Each particle on the wheel travels in a planar circular trajectory (Kinematics of Machinery, 1876).

Velocity

Velocity is a measurement of speed in a certain direction of motion. It is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of physical objects. Velocit
Kinematics
…x ^ + y ( t ) y ^ + z ( t ) z ^ , where x ( t ) , y ( t ) , and z ( t ) describe each coordinate of the particle's position as a function of time. The velocity of a particle is a vector quantity that describes the direction as well as the magnitude of motion of the particle. More mathematically, the rate of…
As a change of direction occurs while the racing cars turn on the curved track, their velocity is not constant even if their speed is.
