Feel The Forces

Yes, that famous temple region, which, if hit just right, can kill you. Fortunately it didn’t. It did however, meet the side of my face and temple, and introduced the rough cast plaster and gravel wall surface with all of that negative force  discussed yesterday.

At speed, the impact probably would have looked very interesting. Even more interesting if it had been filmed with one of those ‘slow motion high-speed capture cameras’. Yes. The multitude of expressions as my face approached the wall. The fear factor, as I was airborne from the bike. Recognition, as I saw I was going to collide with something. Surprise as I recognised it was to be the wall. Panic as I realised I would not be able to prevent this from happening. Realisation, that it was in fact a hard brick wall. Shock as I saw the roughcast cement (with added gravel) was broken in places, and then, the actual impact. A spilt second or two, and an entire gamut and a variety of thoughts and expressions flashed across my terrified features. Someone said to me recently, “You must expend half of your energy in the use of your facial expressions”. I inquired what they were referring to. They likened it to the classic Italian character who talks with their hands as well as their voices. That day I probably would have used a lot of energy on my facial expressions as well.

So the face met the wall and the rest of the body followed. You may recall how I mentioned in the earlier blog of the kite, the stilt, my brother and his injury, (see blog 5th April 2012 ) head wounds tend to bleed very quickly and, a lot. Mine did as well. My face had mashed into the wall at speed, I believe the rest of my body had tried to catch up with my face and achieved a higher point of contact with the wall. I was upside as I hit the wall in full contact. Gravity of course (another set of Laws which Newton wrote down), would not allow me to remain there for long, as the formulae demonstrates.
                               Fg= m1Xm2 /r2 *
 
So of course my body didn’t. There was a moment when all of my face had been as mashed as was possible in the circumstance. Before my body lost its horizontal trajectory and achieved a point of motionlessness. Then the weight and gravity, forced the parts of me, which were lower than my body, towards the ground and bitumen footpath also at a calculable speed. So. We have crash, the bike bounces from travelling car, to parked car and back to the travelling car. Is struck again and flung off towards the footpath. The bike stops at the cement curb, at least the front wheel does. The small wheel size of the Raleigh twenty was an issue here. They only had a 20 inch front wheel. That was part of the attraction, but also a contributing factor to the incident. The cement curbs were about 6 inches in height.
