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 Commonwealth English ) anticlockwise ( ACW ) or (in North American English ) counterclockwise ( CCW ...
Literally, it means to take a course opposite the apparent motion of the sun viewed from the Northern Hemisphere (the face of this imaginary clock is the ground the viewer stands upon). [1] The earliest recorded use of the word, as cited by the Oxford English Dictionary , is in a 1513 translation of the Aeneid , where it is found in the phrase ...
In organic chemistry, an electrocyclic reaction can either be classified as conrotatory or disrotatory based on the rotation at each end of the molecule.In conrotatory mode, both atomic orbitals of the end groups turn in the same direction (such as both atomic orbitals rotating clockwise or counter-clockwise).
In physics, the Coriolis force is a 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. In one with anticlockwise (or counterclockwise) rotation, the force acts to the right.
When counting the total number of turns, counterclockwise motion counts as positive, while clockwise motion counts as negative. For example, if the object first circles the origin four times counterclockwise, and then circles the origin once clockwise, then the total winding number of the curve is three.
Anticyclonic rotation, or anticyclonic circulation, is atmospheric motion in the direction opposite to a cyclonic rotation. For cyclonic rotation, this motion is in a counter-clockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere. Thus, just anticyclonic rotation would mean clockwise in the Northern Hemisphere ...
This definition relies on the fact that every simple closed curve admits a well-defined interior, which follows from the Jordan curve theorem. The inner loop of a beltway road in a country where people drive on the right side of the road is an example of a negatively oriented ( clockwise ) curve.
Cyclonic rotation or cyclonic circulation is the atmospheric motion in the same direction as a planet's rotation, as opposed to anticyclonic rotation.In the case of Earth's rotation, the Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere.
