In electrodynamics, circular polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant magnitude and is rotating at a constant rate in a plane perpendicular to the direction of the wave. In electrodynamics, the strength and direction of an electric field is ...
Left hands make up over 90% of the artwork, demonstrating the prevalence of right-handedness. [ 1] A female student writes with her left hand. In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more dextrous. The other hand, comparatively often the weaker ...
Clockwise. Two-dimensional rotation can occur in two possible directions or senses of rotation. Clockwise motion (abbreviated CW) proceeds in the same direction as a clock 's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in ...
Ambidexterity. Ambidexterity is the ability to use both the right and left hand equally well. [ 1][ 2] When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people. When referring to humans, it indicates that a person has no marked preference for the use of the right or left hand .
Countersteering. Countersteering is used by single-track vehicle operators, such as cyclists and motorcyclists, to initiate a turn toward a given direction by momentarily steering counter to the desired direction ("steer left to turn right"). To negotiate a turn successfully, the combined center of mass of the rider and the single-track vehicle ...
Strafing in video games is a maneuver which involves moving a controlled character or entity sideways relative to the direction it is facing. This may be done for a variety of reasons, depending on the type of game; for example, in a first-person shooter, strafing would allow one to continue tracking and firing at an opponent while moving in another direction.
Chirality (physics) A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality ). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called ...
WASD (,AOE on Dvorak keyboards; ZQSD on AZERTY keyboards) is a set of four keys on a QWERTY or QWERTZ computer keyboard that mimic the inverted-T configuration of the arrow keys. These keys are most commonly used to control the player character 's movement in computer games. W / S control forward and backward, while A / D control strafing left ...
