Inertia vs Decay

 

Newton's first Law of Motion says that an object in motion tends to stay in motion and an object at rest will stay at rest - unless acted upon by an outside force.  

I think this inertia has attacked my blog.

For the first dozen years, I faithfully posted once a day.  Lately, it has been more like once or twice a month.

I can come up with lots of reasons - nothing worth talking about, or something too personal to share, etc.- but I think has more to do with inertia.  The longer I go without posting, the harder it gets to do.

The other possible cause is decay.  There is no such thing as a perpetual motion machine.  Whether from friction or gravity, everything eventually slows down.
