Motion (physics)

In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed. Motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.

If the position of a body is not changing with respect to a given frame of reference the body is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. Momentum is a quantity which is used for measuring motion of an object. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in an isolated system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum.

As there is no absolute frame of reference, absolute motion cannot be determined. Thus, everything in the universe can be considered to be moving.

Wii MotionPlus

The Wii MotionPlus (Wiiモーションプラス) is an expansion device for the Wii Remote video game controller for the Wii that allows it to capture complex motion more accurately. According to Nintendo, the sensor in the device supplements the accelerometer and Sensor Bar capabilities of the Wii Remote to enable actions to be rendered identically on the screen in real time.

The Wii's successor console, the Wii U, supports the Wii MotionPlus and its peripherals in games where use of its touchscreen-built-in primary controller is not necessary.

History

The Wii MotionPlus was announced by Nintendo in a press release on July 14, 2008, and revealed the next day at a press conference at the E3 Media & Business Summit. It was released in June 2009. On May 3, 2010, Nintendo announced that starting May 9, 2010, the company will include its Wii Sports Resort game and MotionPlus controller with new consoles with no price increase.

Development

The Wii MotionPlus was developed by Nintendo in collaboration with game development tool company AiLive. The sensor used is an InvenSense IDG-600 or IDG-650 in later units, designed in accordance to Nintendo's specification; with a high dynamic range, high mechanical shock tolerance, high temperature and humidity resistance, and small physical size.

Motion (software)

Motion is a software application produced by Apple Inc. for their Mac OS X operating system. It is used to create and edit motion graphics, titling for video production and film production, and 2D and 3D compositing for visual effects.

History

The original product, codenamed "Molokini," was demonstrated on April 19, 2004.

At a pre-NAB event in April 2005, Apple released the second version of Motion along with new revisions of the other Pro applications, optimised for the Power Mac G5 and Mac OS X 10.4.

In January 2006 Apple stopped selling Motion as a stand-alone product. Introduced at NAB in Las Vegas on April 15, 2007, Motion 3 was included as part of the Final Cut Studio 2 suite.

Motion 5 was introduced on June 21, 2011. It is available through the Mac App Store at a reduced price of $49.99. Motion 5 is now sold as a stand-alone product.

Motion 5.2 was released on April 13, 2015. New features included 3D titles with extensive material, lighting, and edge options, 12 new generators, keyframe copying & pasting, improved mask and shape creation, and performance improvements.
