In physics, the Coriolis force is an inertial (or fictitious) force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object.
Left-hand traffic ( LHT) and right-hand traffic ( RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. [1] The terms right- and left-hand drive refer to the position of the driver and the ...
In mathematics, a rotation of axes in two dimensions is a mapping from an xy - Cartesian coordinate system to an x′y′ -Cartesian coordinate system in which the origin is kept fixed and the x′ and y′ axes are obtained by rotating the x and y axes counterclockwise through an angle . A point P has coordinates ( x, y) with respect to the ...
Rotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation. A solid figure has an infinite number of possible ...
Optical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.
Rotation of an object in two dimensions around a point O. Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point. Rotation can have a sign (as in the sign of an angle ): a clockwise ...
The controls (stick and rudder) for rotary wing aircraft ( helicopter or autogyro) accomplish the same motions about the three axes of rotation, but manipulate the rotating flight controls ( main rotor disk and tail rotor disk) in a completely different manner. Flight control surfaces are operated by aircraft flight control systems .
A split-view screenshot of Google Maps. In the bottom half Street Maps is shown, while in the top half Street View is shown. A user can zoom in and out of either of them independently of the zoom level of each. As the user drags the map, the grid squares are downloaded from the server and inserted into the page.
