    (a digital camera with an image sensor which size is similar to 35 mm film in film cameras as the standard film camera format) [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.

    en.wikipedia.org/wiki/Linear_motion

    Since linear motion is a motion in a single dimension, the distance traveled by an object in particular direction is the same as displacement. [4] The SI unit of displacement is the metre . [ 5 ] [ 6 ] If x 1 {\displaystyle x_{1}} is the initial position of an object and x 2 {\displaystyle x_{2}} is the final position, then mathematically the ...

    The spread of shots from gun A is much smaller than those for gun B. Also, the MPI of A is off the target area, whereas that of B is on the target area. Figure 2 shows the MPIs of the two guns for five serials fired from each gun on different occasions. All the MPIs of gun B are on the target area, whereas those of gun A are well spread.
