Newton's Dream

[FranktheFrank]

When speaking about speed
We are speaking of velocity in feet per second
If about vectors then we would need to add a direction
Like nor ‘west or such headings

Which leads us to velocity vs time diagrams
Not centripetal or even radial acceleration
But of initial and final velocities divided
By two to give the average

Any distance can be calculated by using
The average velocity by the time in seconds
And the final velocity can be ascertained simply
By adding initial velocity plus acceleration

In feet per second squared. It is a simple matter
To combine these statement to arrive at the equation
V squared minus U squared
Equals twice acceleration by time squared

Which, by the similar process gives
The fascination equation that distance (S)
Equals initial velocity by time
Plus Half acceleration by time squared (in feet).

Sorry, my brain pretends to play dead when math enters into anything. Or maybe it doesn't need to pretend. At any rate, I'm left puzzled. I would much rather read your Dylan Thomas poem you mentioned.

Haha. Just a doodle to expand my range.

It's not really maths, although math is involved.

Sir Isaac Newton invented a news maths
called calculus to take away the boring
long way of calculating the laws of motion.
He actually invented the laws of motion
and they are still used, albeit via computers,
for the space launches and gravitational pull.

This is a description of the old way.
But you have to understand the old way to use
the calculus.

This is him struggling with concepts in dream mode.

I'd forgotten about Dylan.

Well done for writing this, Frank. It's over my head - wouldn't know where to start.

Hi Eira
So nice to see you posting again.
It's just a scribble Eira, I don't think it really to anyone's taste.
I started on my old mechanics/physics books recently. Don't ask me why.
My wife think I am nuts, she would rather me fix jobs around the house.
But I prefer reading and poetry.
We've had a horrendous year with illness, but thanks be to God, we have come through it.
Old age does not come alone.

Thanks for comment.

Basically it means S = u.t +1/2.f.(t squared)
