kinematics the description of motion without regard to force or mass. Three of the most common of such descriptors refer to an object's changes in spatial position, its speed, and its changes in speed. The terms used to refer to these kinematic characteristics are displacement, velocity, and *acceleration.

Kinematic viscosity is the ratio of - absolute (or dynamic) viscosity to density - a quantity in which no force is involved. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density like ν = μ / ρ (2) where ν = kinematic viscosity (m2/s) μ = absolute or dynamic viscosity (N s/m2)
5. Kinematic schematics, Diagrams: A kinematic schematic or diagram is drawing that clearly defines the kinematic nature of a mechanism. In particular, these drawings must clearly show the following: 1) Each body, the number of bodies, and the type of body (binary, ternary, etc). 2) Each joint or kinematic pair, and its type.

The key to controlling robotic systems in a robust manner is kinematic equations. These equations not only describe the geometry of the system; they also allow modern motion controllers with adequate processing power and speed to perform the necessary calculations that provide smooth motion control of the system.

Kinematics doesn't regard the mass of any object in the system to describe its motion, whereas kinetics does. Kinematics can be considered a branch of mathematics. Essentially, it deals with applying a set of equations of motion to solve various physics problems. Kinetics deals with the laws of motion while kinematics deals with the …
