Page orientation is the way in which a rectangular page is oriented for normal viewing. The two most common types of orientation are portrait and landscape. [ 1] The term "portrait orientation" comes from visual art terminology and describes the dimensions used to capture a person's face and upper body in a picture; in such images, the height ...
In the three-dimensional case, the situation is more complicated as now one has horizontal and vertical planes in addition to horizontal and vertical lines. Consider a point P and designate a direction through P as vertical. A plane which contains P and is normal to the designated direction is the horizontal plane at P.
In the standard language ( 표준어; 標準語) of South Korea, punctuation marks are used differently in horizontal and vertical writing. Western punctuation marks are used in horizontal writing and the Japanese punctuation marks are used in vertical writing. However, vertical writing using Western punctuation marks is sometimes found.
v. t. e. A centripetal force (from Latin centrum, "center" and petere, "to seek" [ 1]) is a force that makes a body follow a curved path. The direction of the centripetal force is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. Isaac Newton described it as "a force by ...
Vertical and horizontal subspaces for the Möbius strip. The Möbius strip is a line bundle over the circle, and the circle can be pictured as the middle ring of the strip. At each point e {\displaystyle e} on the strip, the projection map projects it towards the middle ring, and the fiber is perpendicular to the middle ring.
The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals . As movements consist of rotations and translations ...
When air resistance can be neglected, projectiles follow parabola-shaped trajectories, because gravity affects the body's vertical motion and not its horizontal. At the peak of the projectile's trajectory, its vertical velocity is zero, but its acceleration is downwards, as it is at all times. Setting the wrong vector equal to zero is a common ...
Zenith. The zenith ( UK: / ˈzɛnɪθ /, US: / ˈziːnɪθ /) [ 1] is the imaginary point on the celestial sphere directly "above" a particular location. "Above" means in the vertical direction ( plumb line) opposite to the gravity direction at that location ( nadir ). The zenith is the "highest" point on the celestial sphere.
