A natural turn is a dance step in which the partners turn around a common center clockwise. Its near-mirror counterpart is the reverse turn, which is turning counter-clockwise. [1] This terminology is used mainly in the "International Standard" group of ballroom dances. [2] "
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 ...
When turning, a backside turn is analogous to a toeedge turn, and frontside turn is analogous to a heeledge turn. In the air, frontside means that 90 degrees into your first rotation you will be facing forward downhill and backside means that 90 degrees into your first rotation your back will be facing downhill.
In these dances the follower's right arm is normally used to lead a turn (most commonly by the leader's left arm, but sometimes by the leader's right arm when a cross-hand or "handshake" position is used), an inside turn is normally a left (counter-clockwise) turn, while an outside turn is a right (clockwise) turn.
The two-dimensional case is the only non-trivial (i.e. not one-dimensional) case where the rotation matrices group is commutative, so that it does not matter in which order multiple rotations are performed. An alternative convention uses rotating axes, [1] and the above matrices also represent a rotation of the axes clockwise through an angle θ.
The anticlockwise or counterclockwise direction. Widdershins (sometimes withershins, widershins or widderschynnes) is a term meaning to go counter-clockwise, anti-clockwise, or lefthandwise, or to walk around an object by always keeping it on the left.
The turn (symbol tr or pla) is a unit of plane angle measurement that is the measure of a complete angle—the angle subtended by a complete circle at its center. One turn is equal to 2π radians, 360 degrees or 400 gradians. As an angular unit, one turn also corresponds to one cycle (symbol cyc or c) [1] or to one revolution (symbol rev or r). [2]
Counter-rotating propellers generally turn clockwise on the left engine and counterclockwise on the right. The advantage of such designs is that counter-rotating propellers balance the effects of torque and P-factor, meaning that such aircraft do not have a critical engine in the case of engine failure.
