Temperatures should drop when the wind shifts to its normal direction from the south.
By contrast, in the direction normal to the curve, the function has a singularity.
The neck may be stiff and may not move in all normal directions.
The quarter-mile track was run on the front straight, opposite to the normal running direction.
Thus some prior information of the geometry is needed to define the correct normal direction.
Usually its flow is in the normal anterograde direction, from bottom to top.
This function moves from deal to deal in the normal direction of play.
There's a force of over a hundred thousand G's acting in a direction normal to every point of our surface.
These results are equivalent to the dot product between velocity and the normal direction to the area.
This can cause a net force on the object in the direction normal to the side with lower local pressure.
