Feel the Cement Finish

So having proven yet again that Newton was right, or at least his laws of motion confirmed what had been happening since the dawn of time, and he was just one of the people to write it down. And that he was smart enough to tell others about it. I proceeded into the rest of the crash.  There was little happening from here on in, except I was being flung away from the point of contact, knocked in a trajectory that took me away from the forward travelling (though braking) vehicle, and straight towards the raised cement curb. Striking the curb front on (the third law again), I flew not only over the handlebars, and the curb, but through the air (the first law again) and met with Newtons ‘Third Law of Motion’ once again.

Across the bitumen footpath was a light purple/mauve painted brick wall (as I remember it. Though why anyone would paint a wall mauve, particularly a church?) This was the retaining wall of the Anglican church in the valley). A ‘rough cast’ brick wall. You may remember me mentioning this type of wall previously (see blog 5^th August, 2012)? Not just made of bricks, but also covered in a cement plaster mix with small gravel added for texture. Added. The gravel must have been added to increase grazing injury when people scraped against it. I can’t imagine I was the only one. Added to increase complications even though the small stones are supposed to be smooth. The plaster was not that fresh and was already breaking apart in places. It was this wall, which applied the third Law of Motion, to my body again.

When one object applies force on another, the second object exerts an equal and opposite force on the first.

So let’s just examine that again. One object (in this case, my body), applies force (my body flying at speed, so that’s velocity x mass), on another (for this we are using a stationary brick wall). The second object (the wall), exerts an equal (that’s mass of my body) and opposite (that’s mass of my body x velocity….. to the negative) force, on the first (I get stopped). That’s, my mass x velocity = (-ve) my mass x velocity, which unfortunately do not just cancel each other out so nothing happens. But it means the moving object is stopped with the same force it was moving with. You can observe what can happen if you take a lump of plasticine and throw it at a hard surface. It keeps its shape until it meets the wall. The idea of phase particle physics flashes briefly through my travelling mind… not that specific title, but the idea that; if I could increase the resonance of my mass I may have been able to have passed through the wall entirely, but since I don’t possess that particular super power… I just met the wall at speed, and primarily with my face and side of my head.
