The two basic ways practiced in Yoshinkan are the 'ichi' and 'ni' versions that we have for 99% of techniques.
The most basic application of this is from a grabbing attack where a grab and pulling action attack would be the Ichi version of the technique and a grab and push would be the ni technique.
I suspect these are the basic kihon versions you have seen. There are numerous variations for jiyu waza etc which tend to be shorter and make uke hit the ground very hard.
I hope this helps.
