Kinetics

Kinetics (Ancient Greek: κίνησις "kinesis", movement or to move) may refer to:

NCR Self-Service

NCR Self-Service, LLC (known as Kinetics until February 2008), a subsidiary of NCR Corporation, develops self-service software and hardware travel technology. Solutions for hardware include the TouchPort II C for airline check-in and ResortPort for hospitality self-service. Common Use Self-Service technology simplifies the check-in process by allowing passengers one common point of access for check-in.

History

The company was founded in 1988 by David Melnik and acquired by NCR Corporation in 2004. The Kinetics brand and past name has been officially put to rest by NCR in February 2008 and is known as NCR Self-Service, LLC. The company has been split up and downsized three times since July 2007 with NCR reorganizing. The various functions that are left are now being controlled by NCR Retail Division, Atlanta, GA (Hardware Engineering), Theresa Heinz (Program Management) in Lake Mary, FL. Engineering, Field Service, Customer Helpdesk, Accounting and IT are now being handled overseas.

Dynamics (mechanics)

Dynamics is a branch of applied mathematics (specifically classical mechanics) concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to its causes. Isaac Newton defined the fundamental physical laws which govern dynamics in physics, especially his second law of motion.

Principles

Generally speaking, researchers involved in dynamics study how a physical system might develop or alter over time and study the causes of those changes. In addition, Newton established the fundamental physical laws which govern dynamics in physics. By studying his system of mechanics, dynamics can be understood. In particular, dynamics is mostly related to Newton's second law of motion. However, all three laws of motion are taken into account because these are interrelated in any given observation or experiment.

Linear and rotational dynamics

The study of dynamics falls under two categories: linear and rotational. Linear dynamics pertains to objects moving in a line and involves such quantities as force, mass/inertia, displacement (in units of distance), velocity (distance per unit time), acceleration (distance per unit of time squared) and momentum (mass times unit of velocity). Rotational dynamics pertains to objects that are rotating or moving in a curved path and involves such quantities as torque, moment of inertia/rotational inertia, angular displacement (in radians or less often, degrees), angular velocity (radians per unit time), angular acceleration (radians per unit of time squared) and angular momentum (moment of inertia times unit of angular velocity). Very often, objects exhibit linear and rotational motion.
