What do the arrows indicate direction of?
Force arrows are used to represent both the magnitude and direction of forces. The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. The direction of the arrow corresponds to the actual direction that the force is being exerted.
Which way should arrows point?
A simpler way to figure this out is to always make the arrows face the ceiling or wall. If your filter is on the wall, the arrow should face the wall. If your filter is on the ceiling, the arrow should face the ceiling.
Which way do arrows go?

Which way should the arrow point on my air filter?
Remember that air flows from your ducts, through the filter, and into the furnace. The arrow on the filter should always point toward the furnace. The furnace or the filter air box most likely will contain the correct filter measurements for replacement filters or just check the filter itself.
Why do you need directional arrows on tires?
A tread pattern can be designed to disperse more water by making it rotate in only one direction. Thus, the need for directional arrows. The arrow tells you which way to mount a tire for maximum water dispersal. Another, less apparent reason for directional arrows is the tread splice.
Which is the correct direction for an arrow?
An arrow pointing up usually means larger or getting larger, so that should be used for Ascending order. An arrow pointing downwards usually means something is smaller or getting smaller and it should be used for Descending order.
Why does an arrow appear to be reversed?
Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed.
How to draw an arrow in a glass?
Fill your glass of water. Draw a horizontal arrow on a note card. Put the note card behind the glass of water and slowly move the note card back. Look through the glass from the front and observe the arrow.
