Unit Vector Hat

The unit vector hat has the symbols for the three main unit vectors, î (i-hat) ĵ (j-hat), and , (k-hat).  You could say that this is your i-hat, j-hat, and k-hat hat!  Physics chic doesn’t get more geek!

The unit vectors are vectors with a length of one that point in a particular direction.  î , ĵ, and form a set of three mutually perpendicular vectors.  They are similar to x, y, and z, but a bit more generic.  Most advanced physics courses use i, j, and k rather than x, y, and z.

A vector that has a length other than 1 that is pointing in the direction of one of the unit vectors can be expressed by simply multiplying the length times the  unit vector.  For example, a vector that is 5 m long pointing in the i direction would be 5 î

To see how you can add a vector in the î  direction to one in the ĵ direction, see this helpful info.
