There I am running merrily on the treadmill in the basement (not recommended, if you are looking for enjoyment in the activity). I have been going for a while, you know I have a rhythm going, really hitting my stride. Then.......BAM! My finger ever so lightly bumps the magnetic safety key, signally the instantaneous stop of the machine.
Let me stop here to remind you of Newton and his 3 laws of motion:
#1 Every object in a state of uniform motion tends to remain in that state of motion unless external force is applied to it.
#2 The relationship between an object's mass (m), it's acceleration (a), and the applied force (F) is F=ma.
#3 For every action there is an equal and opposite reaction.
So picture these in the context of a person running (an object in motion) on a treadmill, when the floor stops moving (unexpected external force). Do you know what happens? An equal and opposite reaction. In my particular case..... my feet flying back and my face flying into the mile/time counter. Which brings me to the F=ma equation. If my mass, plus my acceleration equals the applied force, I think you will believe me when I say I was seeing stars.
This brings me to my inquiry, and I really need some feedback so I can measure my aptitude to that of a normal person. To be quite honest, I hit that darn safety/death key at least once a run, and it usually ends in pain (and maybe (quite possibly) a few choice words). Does this happen to you or am I just really special?
