(net) Force is a measure of the net thrust exerted on a body of matter to
"move"; or _accelerate_ it. The ratio of the net force [f] to the
acceleration [a] that it causes, is a constant: m = f/a.
(net) Weight is a measure of that particular thrust exerted between
(resting) bodies and Earth's surface; which restrains them from accelerating
centripetally. The ratio of the net weight [w] to the deceleration [g] that
it causes, is a constant: m = w/g.
These ratios [f/a = w/g] are each measures of the "inertness" of the body
The simplest way to measure any of these thrusts is with weight-scales;
which are [usually] designed for use here on Earth; where the acceleration
of free fall averages about 32.174'/sec² [9.81 m/sec²]; where an adjustment
is usually provided on good scales to set them to a reading of zero before
Is this man on a personal journey to discover 17th Century Physics?
Without '17th Century Physics' you woundn't have 21st Century Physics.
Obviously YOU haven't learned anything from Shead (that's probably a
good thing). That isn't the way time works in Dense Donny's
S*head wants to correct the "error" made in the introduction of the
metric system in the 1790s, by going back to the gravitational fps
system with the slug, something that wasn't invented until the 20th
century and which didn't appear in physics textbooks before 1940 (and
which has pretty much disappeared from them now).
He does this in part by pretending that pounds, which have been units
of mass since they were first used, and which are most often units of
mass today, do not exist. He instead pretends that the pound force, a
recent bastardization (done to only one of the hundreds of different
pounds used throughout history) that was never well defined before the
20th century, is the only pound that ever existed.
The sad part is that there are today many science teachers (especially
in the U.S.) who are just as stupid as Dense Donny on that last point,
and worse yet, there are now a few textbook authors who were so poorly
educated themselves that they believe the same nonsense.
Time flies like an arrow;
fruit flies like a banana.
