Inertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion. It is proportional to an object's mass. The principle of inertia is one of the fundamental principles of classical physics which are used to describe the motion of matter and how it is affected by applied forces. Inertia comes from the Latin word, iners, meaning idle, or lazy. Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica, which states:
The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line.
With three weeks in the books and week four beginning I feel good...really good. Week three was the best week of runs so far. I ran 3.4 miles Tuesday, 4 miles Thursday and I had a great run Saturday it was shorter distance week (5 miles), but since week two's run was a disaster, I felt good so I tacked on another mile and half loop. I blame week two's demise on The Colossus World Tour (and my love of a good time and beer). I was at the Judge's Bench Friday Night hanging out and then tried to run 7 miles Saturday Morning a touch dehydrated and then i had an idea of a quick make up run Sunday morning it was quickly traded for 'Pints and Pancakes' at T-Bonz. I had such a successful bounce back this past week that I am actually looking forward to this weeks work outs as I start tacking on more miles. I actually feel a good bit more overall energy when I keep up with my work out plan and I am moving around with the girls schedule and bike rides. When I stop though, I grow roots quick and it takes some effort to get moving again (especially if I have a beer in hand).
I guess you have to have a bad week or two to know what a good week looks like. Four Miles Tuesday, four mile run this Thursday then Xmas in July that night at DuClaw @ Arundel Mills come by and say 'hey' while I am stretching and keeping my legs from cramping up while I prepare for 9 miles come Saturday.
