If you use the Aperture Priority then you are leaving it to the camera to select the shutter speed, and it will base that on the amount of light it is getting from whatever Aperture setting you use. You won't get a crisp 'frozen' image from moving objects as often. Most times it will come out blurred. The H subsetting there is likely for High Speed (ie. burst mode) I think. Someone who uses Nikon can tell you better than I could.
Another option for you would be to select Scene, and choose 'Sports' or something similar.
Jump on YouTube and watch a couple of tutorials if you don't have time for a course.
