For a reverse throw the club rotates the 'same' direction as a rolling wheel-rolling in the same direction-would rotate, such that the handle comes down into the catcher's upturned hand.
Simple logic circuits interpret the relative timing to indicate which direction the wheel is rotating.
The direction of the electric field however steadily rotates.
In circularly polarized light the direction of the electric field rotates at the frequency of the light, either clockwise or anticlockwise.
When this happens, the engine starts rotating with the rest of the rocket (regardless of its shape) and the direction of thrust rotates as well.
There are scoring zones at each end of the table so that direction of play can rotate after each frame, or so that teams can play both directions during one frame.
Specifically, given that this is a circularly polarized plane wave, these vectors indicate that the electric field, from plane to plane, has a constant strength while its direction steadily rotates.
The domains are separated by thin domain walls a number of molecules thick, in which the direction of magnetization of the dipoles rotates smoothly from one domain's direction to the other.
Instructions on the tube state what direction to rotate it.
As the screws rotate in opposite directions, the pumped liquid moves along the screws spindles.
