  2. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration). The motion of a particle (a point-like object) along a line can be described by its position x {\displaystyle x} , which varies with t {\displaystyle t} (time).

  3. Watt's linkage - Wikipedia

    en.wikipedia.org/wiki/Watt's_linkage

    Such devices had to combine engineering simplicity with a high degree of accuracy, and the ability to operate at speed for lengthy periods. For many purposes approximate linear motion is an acceptable substitute for exact linear motion. Perhaps the best known example is the Watt four bar linkage, invented by the Scottish engineer James Watt in ...

  4. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    Linear motionmotion that follows a straight linear path, and whose displacement is exactly the same as its trajectory. [Also known as rectilinear motion] Reciprocal motion; Brownian motion – the random movement of very small particles; Circular motion; Rotatory motion – a motion about a fixed point. (e.g. Ferris wheel).

  5. Linkage (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Linkage_(mechanical)

    James Watt's parallel motion and Watt's linkage; Peaucellier–Lipkin linkage, the first planar linkage to create a perfect straight line output from rotary input; eight-bar, one DOF. A Scott Russell linkage, which converts linear motion, to (almost) linear motion in a line perpendicular to the input.

  6. Cam (mechanism) - Wikipedia

    en.wikipedia.org/wiki/Cam_(mechanism)

    The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.

  9. Action (physics) - Wikipedia

    en.wikipedia.org/wiki/Action_(physics)

    In the simple case of a single particle moving with a constant velocity (thereby undergoing uniform linear motion), the action is the momentum of the particle times the distance it moves, added up along its path; equivalently, action is the difference between the particle's kinetic energy and its potential energy, times the duration for which ...
