Your speed should be correct and stable by let say at the latest 200ft on approach and if not then go around, your speed at the threshold must be confirmed as correct or go around. Forcing the aircraft onto the ground because you are too fast is pointless and is full of hazard as you experienced.
If you had decided to stop and not go around you may not have stopped before the end of the runway. Lift is a function of speed so if you are too fast the wings will be generating too much lift with poor friction with the ground, like being on ice, braking therefore may also be ineffective and could lead to a loss of control when applied.
Landing distances are calculated from 50ft above the threshold and at the later stages of the landing roll normal breaking (i.e. the brakes not slammed on) It is normally possible in light aircraft to touch down at the threshold at the correct speed.which offers a considerable benefit over the landing distance. The C152 POH informs that the landing distance is 1200ft (366m ) but the landing roll is 475ft (145m). The airborne part is approximately 40% of the whole distance. The PA28-161 gives a landing distance of 1135ft (346m) and the roll 625ft (191m) The airborne part being 55% of the overall distance.If you touch down too fast you will lose a large part of these benefits if not all of it.
Of course the above calculations will vary with density altitude, w/v and aircraft weight. Pilot DAR's contribution is excellent in my view.
