Holy crap! A few things happened this week that all blend together to help me understand one idea….INERTIA.
Newton’s first law, Duke basketball, and my third year running the Green Legs and Hamstrings trail race.
First of all, my Clark Kentesque personality during the day is mild mannered 8th grade physical science teacher. This week we learned the classic “Newton’s 3 Laws of Motion” concept and if you don’t remember Newton’s 1st law is thus:
An object in motion stays in motion and an object at rest stays at rest, unless acted upon by an outside force.
This is the idea of inertia.
Here’s another way of putting it:
It’s a challenge to build momentum. Starting something new is really hard. The beginning is the most difficult part. Once something is already in motion it gets easier and easier. Eventually it’s hard as hell to slow down. After awhile, stopping is nearly impossible.
