Is Gc (32.2 lbmft/lbfs^2) equal to gravity? I think it is, but I'm kinda confused about the whole concept. Could someone explain it to me? Thank you very much.

1 answer

In English units, the acceleration of gravity near the surface of earth is about 32 feet/second^2 = g

When we used those units, we defined mass in slugs.
mass in slugs m = weight in pounds/g = weight in pounds/32

Then we could use Newton's second law
F = m a
where force is in pounds, mass is in slugs and a is acceleration in feet/second^2

In Physics we use SCI metric units these days.

Force in Newtons = mass in kilograms * acceleration in meters/second^2
