This motion is generated directly either by the water and wind motion, particularly lateral wave motion, exerting forces against the hull or by the ship's own propulsion; or indirectly by the inertia of the ship while turning. This movement can be compared to the vessel's lateral drift from its course.
The legs of water beetles have little hairs which spread out to catch and move water back in the power stroke, but lay flat as the appendage moves forward in the return stroke. Also, one side of a water beetle leg is wider than the others and is held perpendicular to the motion when pushing backward, but the leg rotates when the limb returns ...
The squat effect is the hydrodynamic phenomenon by which a vessel moving through shallow water creates an area of reduced pressure that causes the ship to increase its draft (alternatively decrease the underkeel clearance of the vessel in marine terms) and thereby be closer to the seabed than would otherwise be expected.
A 4-plane Multiplane background. The lowest plane, furthest from the camera, is only a rendering of a water surface. The plane above it contains (in addition to a cliff with a waterfall) a moving distortion glass, giving a ripple effect to the water. Note how the plane closest to the camera (dark tree in foreground at left) is strongly out of ...
Three Canadair CL-215 amphibious flying boats. The following is a list of seaplanes, which includes floatplanes and flying boats.A seaplane is any airplane that has the capability of landing and taking off from water, while an amphibian is a seaplane which can also operate from land.
An air or water mass moving with speed subject only to the Coriolis force travels in a circular trajectory called an inertial circle. Since the force is directed at right angles to the motion of the particle, it moves with a constant speed around a circle whose radius R {\displaystyle R} is given by:
Traditional animation (also called cel animation or hand-drawn animation) is the process that was used for most animated films of the 20th century. [61] The individual frames of a traditionally animated film are photographs of drawings, first drawn on paper. [62] To create the illusion of movement, each drawing differs slightly from the one ...
Man rowing in slow pace typical for long distances. In rowing (sport), the stroke is the action of moving the oar through the water in order to propel the boat forward. The two fundamental reference points in the stroke are the catch where the oar blade is placed in the water, [1] and the extraction (also known as the 'finish', 'release' or 'tapping down') where the oar blade is removed from ...
