The first, to capture something moving and for it to be blurred in the image.
The second, to capture something moving and for it to be sharply focussed in the image.
I used the Shutter Speed Priority setting on my camera (Tv - time value), and created the following images;
Settings for images are as follows:
Fig 1. F/14, 1/125 sec, ISO-200
Fig 2. F/20, 1/60 sec, ISO-200
Fig 3. F/4.5, 1/800 sec, ISO-200
Fig 4. F/5.6, 1/500 sec, ISO-200
In the first 2 images, the subject is blurry. For both, the aperture was high and the shutter speed was slow.
In the last 2 images, the subject is in focus. For both, the aperture was low and the shutter speed was fast.

I tried the same thing again with my mad family having a run around in the garden. In the first image, the subjects are sharper (although the image isn't as sharp as if I'd used a tripod!). The camera settings for this were F/4.5, 1/800 sec and ISO1600. I forgot to change the ISO to 400 which would've produced a photo will less noise.

I then set the camera to F/14, 1/50 sec (and forgot to change the ISO to 400 so it remained on 1600) in order to make the subjects look blurry. This is the result:
I was successful with the results that I'd set out to achieve, but had I used a tripod and changed the ISO to 400, the images would look better.
