ME02 – Momentum is gained & lost….. you ‘dial it up’ and you ‘dial it down’


Summary….. Here is a help file to get a grip of these points:

Introducing a newly coined phrase: You ‘dial it up’ and You ‘dial it down’
* You (the driver) ‘dial it up’.
… A driver is the responsible person to get a vehicle moving:
… It is the driver therefore, that….. ‘dials up’ the momentum (accelerates the vehicle… safely)
… This makes the driver responsible for the vehicle’s momentum.
* You (the driver) ‘dial it down’.
… A driver is the responsible person to get a vehicle stopped:
… It is the driver therefore, that….. ‘dials down’ the momentum (slows the vehicle… safely)
… This makes the driver responsible for the vehicle’s momentum.

Do not transfer it
– A driver is responsible for their vehicle’s momentum.
– To stop safely, the driver must “dial down” ALL of it, themselves.
– If in collision with anyone or anything…. momentum between all involved will be transferred between all involved… and so….
Therefore the driver would have failed to “dial down” ALL of their momentum THEMSELVES… (this is unacceptable… this is unsafe).

Drivers Momentum Checklist:
1. Dial it up and dial it down… you are responsible for ALL of it
2. Manage it in between… you are responsible for ALL of it
3. You have no right to transfer ANY of it, to anyone or anything else.

 

Introducing a newly coined phrase: You ‘dial it up’ and You ‘dial it down’
A new phrase has been coined here, to help bond a driver of a vehicle, with it’s momentum. The purpose of the bonding, is to create a driver-owned responsibility for ALL of their vehicle’s momentum.
You ‘dial it up’ and You ‘dial it down’.
* ‘you’ = a driver
* ‘it’ = momentum (being the total quantity of momentum)

For the… You ‘dial it up’… bit:
As explained in ME01… When a driver accelerates a vehicle…. the vehicle has more momentum than before… so it gains some momentum.
Now here in ME02… Part of the newly coined phrase, makes this point, a little more catchy
You ‘dial it up’
– You (the driver) ‘dial it up’.
– A driver is the responsible person to get a vehicle moving:
– It is the driver therefore, that….. ‘dials up’ the momentum (accelerates the vehicle… safely)
– This makes the driver responsible for the vehicle’s momentum.

For the… You ‘dial it down’… bit:
As explained in ME01… When a driver slows a vehicle…. the vehicle has less momentum than before… so it looses some momentum.
Now here in ME02… Part of the newly coined phrase, makes this point, a little more catchy
You ‘dial it down’
– You (the driver) ‘dial it down’.
– A driver is the responsible person to get a vehicle stopped:
– It is the driver therefore, that….. ‘dials down’ the momentum (slows the vehicle… safely)
– This makes the driver responsible for the vehicle’s momentum.

 

Relating this to road safety:
This relates to a driver’s awareness that the driver is the responsible one for the vehicle’s momentum….. ALL of it….. in relation to the road surroundings and other road users….. Here are a couple of examples of how it applies.

* Safe….. This ‘dial it down’ example….. is acceptable driver conduct:
… To slow and stop a vehicle…
… in a controlled & suitable amount of time & distance, without the vehicle striking anyone, or anything else.  
is the same as:
… To 'dial down' all the vehicle’s momentum….. back to “none” (stationary)…
… in a controlled & suitable amount of time & distance, without the vehicle striking anyone, or anything else.

* Unsafe….. This ‘dial it down’ example….. is unacceptable driver conduct:
… To slow and stop a vehicle… whilst also striking a small child:
is the same as:
… To be  'dialing down' some of the vehicle’s momentum (slowing), as described in ‘Safe’… (above).
then, at the point of striking the small child:
… The transferring of some of the vehicle’s remaining momentum, to the child, OCCURS….. Noticeable, as the small child now bounces along the road (an object moving has some momentum)
When the child becomes stationary, after bouncing  and scraping along the road, it will THEN have lost the momentum that YOU (the driver) transferred to it.

Obviously this is horrendous, regarding striking a small child….. SO, HERE IS THE POINT:
A driver is responsible to ‘dial down’ ALL of the vehicle’s momentum, themselves.

* A driver is fully responsible for the FULL quantity of momentum, he or she ‘dials up’, regarding the vehicle they are driving.
* A driver is fully responsible for the FULL quantity of momentum, he or she ‘dials down’, regarding the vehicle they are driving…. ALL of it needs to be dialed down safely… to have the vehicle stopped… safely
You (the driver) have no right to transfer ANY of it, to anyone or anything else.

 

Do not transfer it
– A driver is responsible for their vehicle’s momentum.
– To stop safely, the driver must “dial down” ALL of it, themselves.
– If in collision with anyone or anything…. any momentum between all involved will be transferred between all involved… and so….
Therefore the driver would have failed to “dial down” ALL of their momentum THEMSELVES… (this is unacceptable… this is unsafe).
Simplified example of a transfer situation, is given above (* Unsafe…)

 

Drivers Momentum Checklist:
1. Dial it up and dial it down… you are responsible for ALL of it
2. Manage it in between… you are responsible for ALL of it
3. You have no right to transfer ANY of it, to anyone or anything else.

Previous part is:
ME01 – Momentum is a quantity….. you have ‘none’ or you have ‘some’
Next part is:
ME03 – Momentum is variable….. you change the mass and/or you change the velocity

 

* MOMENTUM is relevant for road safety.
* An awareness of momentum = an awareness of, mass, speed and direction…. all are relevant.
* An awareness of momentum = awareness to creating safer roads.

      That is nicely catchy and remains clearly relative to the roads.
      Nicely pitched.
      To gather the physics bit to an everyday worded summary and relate it to the driver direct is apt thinking.
