Inertia is silent?

[bernard]

In another topic, I brought the notion of inertia in our movement. Inertia is largely used in Nature and human beings. Why use muscular strength when we can use inertia to replace an eventual cost of energy?
Inertia has a poor role in slow movements but is ever involved with speed motion. Realizing a movement with or without inertia brings major difference in the motion inputs/outputs loop.

If you move fast, brain gets less information and then more problems?
Do you share this thought?

I like this idea Bernard. I think inertia can be used as a tool. Certainly when people get the "feel" of inertia and how it can help them, for example, to carry through a movement with less effort and more 'grace', it's a help. The brain can sense "ease" as well as "effort". Maybe inertia is like oil, reducing friction between 'action neuromodules'.. or like ball bearings. I agree that people who try 'too hard' to do things end up with problems. Better if they would let their brain figure out how to "do" it first, then just follow that program with their bodies!

Watching anyone work at anything is a real education. You can spot the people who have inherent appreciation and use of inertia, they seem to get the job done with less effort and less energy expediture. My dad used to putter in the farm yard. It looked like puttering, but he got an amazing amount accomplished. Same with my mother, she never moved quickly doing anything, but she rarely stopped moving. Nothing brisk about either of these two, yet somehow it all got done. (I think I inherited their approach, overcoming my own body inertia is usually the hardest part, but once I'm rolling, I just keep going...) It's certainly not an athletic approach and we inertia users tend to put on weight. Always a new set of considerations with each strategy!

Hi Bernard &Diane:

i agree with your thoughts .

bernard,

i think to some what energy -consuming may result in lazness,the person being less intend to move :!: :?:

Hi Somasimplers,

Definitely Nature is lazy! We use already, without knowing it, inertia.
I did not thought to use it as a tool but it is an idea?

Inertia involves a tricky brain calculation!

In my view, motion with inertia (quite all movements have inertia) needs anticipation. Brain is a chess player that moves the pieces in advance. Brain knows (in its memory) all the games (it had played them) but inertia pushes it to play them blindly. It moves in advance and has a feedback of the real move a long moment after!

How does it react if the piece is not a the place it played?

Hi Bernard:

Yes, the idea could develop to be a tool :!: :idea:

I think inertia does not push the brain to play blindly ,but push the brain to play ,enter the game parts.
