Introduction – Cave Wall Media creates concept project ideas for education & intrigue. This project is named “Momentum Exists” and is about road safety.
This concept…. to introduce an awareness to a drivers responsibility of their vehicle’s “momentum”….. as momentum includes two new terms, being… “mass” and “direction“… both offering an evolution on the existing use of the term “speed” and it’s already well established relevance to road safety.
Momentum (p)
relates to the “mass“(m) of an object
and its “velocity”(v). (velocity being a speed and a direction).
… and is simply written
p = m v
No need for the math… No need for the science… Just need to figure:
p = m v
momentum (p)… involves:
‘mass‘ (m), ‘speed‘ and ‘direction‘ (v)
ALL three are relevant to road safety
A driver is responsible to:
Be aware of… therefore safely manage…
ALL three.
Drivers should:
Manage your vehicle’s… ‘mass‘, ‘speed‘ and ‘direction‘
Manage your vehicle’s… momentum
Manage your ‘p’
These terms may not yet be widely known, but this project could highlight that they are relevant to road safety and also that the general public is capable of receiving an understanding of these extra terms….. and their value to the road users.
It will be the purpose of Momentum Exists, to find a range of methods, to introduce the concept of “momentum”, to the general public, in a way that will stimulate a knowledge for and of, it’s relevance towards road safety.
Like this image… developed and published Sept 2025; … more to make new bubble-pic image series, to follow in 2026.

2026 JANUARY UPDATE… A series of 5 Bubble-Pic images have now been designed and published. Created in the CaveWallMedia (design) forge… they have conversation starter areas of substance, with a subtle playfulness in amongst.
continuation… original concept…
Safe momentum:
* All driven (moving) vehicles have some momentum. This has been “dialled up”, by the driver….. safely.
* All stopped vehicles no longer have any momentum. This has been “dialled down”, by the driver….. safely.
These 2 situations demand awareness and responsibility from the driver, to enable safe road use
Unsafe momentum:
* Crashed vehicles will have “transferred” their momentum out in part through the persons or objects struck…..
* Dangerously driven vehicles will threaten and endanger, to do as said, regarding crashed vehicles…..
These 2 situations demand awareness, responsibility, prevention information and perhaps extended punitive tariffs, to prevent this and thus enable a safer road use.
Both safe and unsafe momentum:
An awareness regarding momentum should enable an extra awareness to what is considered safe or unsafe driving. (both as a driver and as a driver being watched and judged by other road users).
Simple example:
(all at same speed and distance)
* A small car tailgating another small car is a threat to the safety of the small car in front.
* A 4×4 or lorry tailgating a small car is a GREATER threat for the safety of the car in front.
…… the latter have a greater mass, therefore, relatively, a greater momentum.
…… the greater threat comes from the tailgating drivers (in the event of a collision) transferring greater amounts of their own momentum, to the car in front.
A driver is responsible to ‘dial down‘ their own momentum (to stop)….. so any transfer is unacceptable…. thus:
a larger massed vehicle (tailgating) poses a greater act of driver irresponsibility.
…… a selfish driver, knowing others are aware of this, may influence conduct and so may deter or reduce occurrence.
…… as mass is measurable, this awareness, may influence a change to afford greater punitive tariffs, according to mass of vehicle driven… (tailgater’s awareness of this may deter future occurrences)
Here is a soft version…
(highlighting absolutely no maths or science need be involved)
Quantity of momentum = “some” or “none”
A road user’s journey is made up of being moving and being stopped.
A vehicle, when moving, has a quantity of momentum = “some”
A vehicle, when stopped, has a quantity of momentum = “none”
A vehicle with a momentum = “some”….. can cause crash hurt and damage
A vehicle with a momentum = “none”….. cannot cause crash hurt and damage
Therefore a driver needs to manage their momentum ‘p’, responsibly… soooooo…
Manage your ‘p‘
Here’s a catchy phrase version…
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)
Therefore a driver needs to manage their momentum ‘p’, responsibly… soooooo…
Manage your ‘p‘
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.
Momentum – fresh and relevant.
A road safety concept with momentum as the key word, would allow packets of inspirational and educational type road safety messages (new fresh words and thoughts for the public).
* Momentum (p)….. is mass (m), the vehicle and all in it….. and includes velocity (v), being the speed in a direction
* Momentum (p) = mass (m) with a velocity (v)
* p = m v
* The ‘m’ bit on our roads…..
vehicles on the same road, are a mix of different masses….. this is relevant.
* The ‘v’ bit on our roads…..
vehicles on the same road, need safe spacing….. speed adjusting and directional responsibility….. are both relevant.
Momentum brings awareness to:
mass, speed and direction….. ALL three are relevant to safe roads.
General public road users may benefit from a knowledge and awareness that….. momentum exists…. regarding vehicles.
Drivers are, after all, responsible, not just for their vehicle’s speed, but for the size and its load, as well as its spatial positioning, when on our roads….. especually in relation to others.
Posters pending…(5 now published)….. as an aid to an awareness type of campaign.
To help visualise the initiative, these posters, have been designed to initiate discussion, stimulate further designs and evolution of the notion “MOMENTUM EXISTS”, perhaps in an awareness campaign.
1. p = m v… MOMENTUM EXISTS – MANAGE IT SAFELY
2. Spot The Pea-Brain… MOMENTUM EXISTS – KEEP YOUR DISTANCE
3. Think Bike (green ticks)… MOMETUM EXISTS – DON’T MAKE IT HIT YOU
4. Velocity Alert (amber red)… MOMENTUM EXISTS – DON’T MAKE IT HIT YOU
5. To stop, brake safely… MOMENTUM EXISTS – MANAGE IT SAFELY
6. Dial it up down… MOMENTUM EXISTS – MANAGE IT SAFELY
Formats, such as posters, videos and info sheets, should suffice to stimulate discussion and learning about relevance of momentum on our roads and road safety.
These formats could be offered to the general public, with a mix of serious and humorous takes.
Presenting the subject matter in a clear manner, will take thought and work, here, behind the scenes….. and may contribute a little more to the road safety of people and property

continuation… original concept…
End Note
The general gist that momentum can be considered relevant for road safety…. may now be clearer….. it was deemed relevant and so this concept was considered worth honing for public awareness and introducing… for perusal… for consideration… for an evolved safety on our roads.
