i have a d3000 and a speed flash for it but i cannot get the shutter speed to go any higher than 200 with the speed flash.is there something im not doing right or is that as fast as you can adjust it ith a speed flash?

welcome to Nikonians.
The flash synchronization for shutter speeds is nearly for all cameras the same. Some have 1⁄200 some have 1/250.
Let me explain it this way:
Before understanding sync speed, you must understand flash duration as well. Flash duration is the amount of time the flash stays on. There's 2 methods of measuring flash duration but suffice it to say that the flash duration is anywhere from 1/8000 to 1/20000 sec, much higher than any camera shutter speed.
Now imagine the shutter mechanism of the camera. There are 2 curtains. Think of this in slow-motion. As you trip the shutter, the first curtain goes first across the frame, exposing part of the frame until it reaches the other side. For slow shutter speeds, the first curtain reaches the other side BEFORE the second curtain starts its travel across the frame, i.e. the whole frame is open for an amount of time. At high shutter speeds, the second curtain starts to move before the first curtain has travelled across. This makes for a slit moving across the entire frame. Since flash duration is much faster than the camera's shutter speed, using flash at these settings will expose only a slit of the frame.
This brings us now to sync speed. It's the camera's fastest shutter speed at which the first curtain has travelled all the way across before the second curtain starts to move. In other words, this is the faster shutter speed at which the shutter mechanism remains wide-open. Normal-sync is a settting that tells the flash to "fire" when the first curtain has reached the other side.
