i dont know if the fiesta mk6 speedo is electric or mechanical, but if were mechanical, it would either be a bad speedo cable, a bad speedo, or a bad gearbox. if it were electrical, i would think that again it could be the speedo, or it could be the wiring, the sensor, or a computer if there is one

What would cause a speedometer to start bouncing at 20 -25 mph?
the LACK of LUBE or Graphte on the speed0 cable IF it's not an electric sending unit type. The speedo cable spins inside another cable. Moisture will cause rust after a few years and this will cause the speedo cable to start to drag and release. If you remove the cable from the back of the instrument cluster and squirt in some graphite, this should help with the bouncing.
What would caused the speedometer to go crazy and jump all over the place?
If it is a cable driven system, usually a jerky needle is caused by a dry cable, either replace or lube the cable as it is getting stuck and stopping for a second then getting unstuck and jumping back to current speed. If it is an electronic speedo then it could be a loose connection under the car, usually they tie into the transmission to get speed input. Or could be as worse as a faulty speedo in the dash.

What kind of speed does a speedometer show in a vehicle?
Acceleration is not represented on a speedometer, however, when you look at the speedo, if the needle is moving, you can get a rough idea of acceleration like this: If the needle is going clockwise (of generally indicating faster speeds) - you are accelerating. If the needle is going anticlockwise - you are decelerating. Speedometers measure speed. You would need an accelerometer to measure acceleration.
