How to capture a photo in slow mo so it looks like it's moving?

Like when you see a photo of a car moving and there's light streaks i'm trying to do that with small game dice! I'm using a Nikon D3100 DSRL. What iso, f-stop, and exposure would i use?

It envolves your shutter speed. Slow it down to capture that effect. Aperture or f-stop controls your depth of field, ISO is the sensitivity to light entering your cameras sensor, and Shutter speed controls the movement your are looking for in your photo. The faster the shutter the more frozen in time you will find things, whereas the slower the shutter speed the more you find the streaks you are looking for.

Now remember that sense you are allowing for longer shutter speed set your ISO to a lower setting since you are giving more time for light to enter your cameras lens. If you want more in focus then set your f-stop to a higher setting, the lower it is the more things are out of focus or the narrower your field of focus.

Shoot at a slow shutter speed, 1/15th or slower and use your flash with it set to fire using the rear curtain sync.

You will have do determine the ISO and lens aperture on your own, using you understanding of basic photographic techniques

The above answers are correct, but I would add that if you're looking for some nice motion streaks behind the dice, with a sharp, "frozen" subject at the end, instead of just blurry streaks and nothing more, you need to use something called "rear curtain flash," or "2nd curtain flash" which will fire your flash at the end of the exposure and freeze the dice at the end of their motion trails. You should be able to find in your manual how to set that up using your menus without too much difficulty.
