To Move Something
You've seen 動く hopefully, and know it means to move. This is similar to that, but now you're moving something else. You know this because as you go to move something the thing you're moving starts to cuss (かす) you out because it's angry.
うごかす
The reading for this can come from 動く. If you know that word, you know how to read this word!
