[Intro]
The drag physics rag
Mass times velocity
(Don’t forget the density!)
[Verse 1]
Flow forces scale
(Aware of the square)
Forces never fail
(There! Became aware)
[Bridge]
The drag physics rag
[Chorus]
Mass times velocity
(Don’t forget the density!)
Oh, once you feel the flow
(You’ll be the first to know)
[Verse 2]
The rain will reign
(The winds will wail)
Skulls feel the pain
(… landslides prevail)
[Bridge]
Ohh, and the damn dams fail!
(The drag physics rag)
[Chorus]
Mass times velocity
(Don’t forget the density!)
Oh, once you feel the flow
(You’ll be the first to know)
[Outro]
Mass times velocity
(Don’t forget the density!)
Oh, once you feel the flow
(You’ll be the first to know)
The veracity (and tenacity)
Of instant karma intensity
(The man show:)
Feel the flow
(There ya go!)
Buy (bye-bye)
By-and-by
(bye-bye)
[Outro]
The drag physics rag
(Don’t be left holding the bag)
ABOUT THE SCIENCE: Violent Rain
One physical result of warming is the formation of larger raindrops, as well as an increase in the number of raindrops falling per square foot. Momentum of Rain is defined by the equation p = mv (where p = momentum, m = mass, and v = velocity). Mass and velocity are part of a larger equation that includes density. Together, these variables increase the intensity of flow forces (flow dynamics). Wind and water flow forces scale with the square of velocity (v²). As flow speeds increase — due to heavier rain or more intense heating — damage scales as the square of that increase.
According to drag physics, force is proportional to density multiplied by the square of velocity (v²). For example:
- A 20 mph wind exerts 4 times the force of a 10 mph wind.
- A 40 mph wind exerts 16 times the force of a 10 mph wind.
- A 50 mph wind exerts 25 times the force of a 10 mph wind.
- A 60 mph wind exerts 36 times the force of a 10 mph wind.
Density further multiplies this force. Water is about 800 times denser than air, so a 10 mph flow of water exerts 800 times the force of a 10 mph wind. As flow velocities increase due to climate change, the resulting forces and damage scale exponentially. While the exact rate of velocity increases with climate change remains under study, we are already seeing the impacts as flood systems fail, sewage systems overflow, and hillsides collapse under the amplified force of violent rain and runoff.
