so I'm trying to crank out F=M*A
my 2ducks say M = 6 * 10^24
also speed is 460 M/S (67,000 mph)
I'm hung 'cuz there is no :dontknow: acceleration, the object (earth:) is a "constant" speed, well it lost a millisecond over the last 100yrs :icon_biggrin:
so do I square the S anyway?
thanks

I don't even understand the problem. Are you moving the earth or flying away from it? Is there a picture?

:l2:
what I'm looking for is a quick way to equate a near impossible feat
I want to 'splain to someone quick;
ya, if you get 7 billion folks all "pushing" at once we can generate X force, the "rock" we're on is producing Y force so we gotta do that ALOT, kinda thing
for the one that "bite' I do want to have a math starting point for further consideration, BUT I don't want to re-learn vectors, angular velocity, ettal :laugh:
Back to the problem;
If any object has a constant speed do you assume Acceleration = 1 in the simple F = M*A?
I get that we're moving with the rock n it's not a great example, but just the fact the rock weighs 6 X 10^24 kg I gotta do something with that :laugh:

Still not understanding your question.
In free space, if velocity is constant, there is no acceleration.
On the surface of the earth, constant velocity (including zero), we "feel" a 1 Gee acceleration due to gravity.
If I build a rocket, with thrust equal to (earth) weight, and run it far from any gravity-mass, it will accelerate at 1 Gee and gain speed quickly.
If I start that rocket on the earth's surface, 1 Gee thrust will make it light on its pad but it will not lift. (The big Saturn V lifts at about 1.2 Gee thrust, so 0.2 Gee net acceleration, and is accelerating slower than a Geo for a while, until its mass is reduced by fuel burn.)
If all the people on Earth pushed the same way, what would they push *against*? Yes, I can push East on a tree, but my feet push West. I'm not going to move the earth, just strain a small section of soil. (With an excavator I can push the tree hard enough to rip soil, but also make skid-marks under the treads. The earth as a whole does not move.)
If all the people on earth were bunched-up in a group, and "pushed with their feet", each person has 8,000 miles of rock under their footprint. Even if they had a stick reaching to the moon so they could exert push without causing a matching pull on the earth, the mass of rock per person is 6,000,000 times the weight of a person, so while we-all could "move the earth" it wouldn't move much.
It is almost exactly the 52nd anniversary of "Levitating the Pentagon" (https://wagingnonviolence.org/2012/10/the-day-they-levitated-the-pentagon/). "No one claims that the Pentagon actually moved. Maybe there was a mistake in the incantation." However they did have a Permit to lift the Pentagon, but only 3 feet (reduced from 300).

Thank you
did FINALLY figure it out, gravity is what hung me :think1: (hung me up a few times climbing also :)
so while we-all could "move the earth" it wouldn't move much.
yep, my eventual point.
workin up a translator from logical thought human to emotional based versions. WAY harder than communicating with guitar types :icon_biggrin:

my current gig has me playin volatiles n lead dust, so.....
Freq = 22,000 yrs
dividing by 1 gets me .000045455 yrs, not very helpful, so;
I X 12 months X 365 days X 24hrs X 60 min to get 286.9776 minutes, useful.
IF I got on the right conversion bus :dontknow:
-
Years is time, frequency is hertz, dividing by one isnt much of a change. Which planets month are 365 days i wonder?
-
Years is time, frequency is hertz
thinking that's the bus I shoulda started on; I'm trying to get to the bus for miles, feet, inches
should be done with volatiles n lead tomorrow :w2:
