The mass of a tree

[Fig]

My good friend owns the largest grow in Montana and delivers to over a thousand patients.

Between a college closet and his commercial operation that big CO2 generator was the thing I was totally clueless about. I can't remember how much it pumps out, but I'm pretty sure it was even higher than 1000ppm.

There is ice core data that supports the "CO2 controls the atmosphere" theory, and some that completely "disproves" it. The religious fanatics who point to ice cores and historical amounts of CO2 are either misinformed, or their fanatical belief is trumping real science. Those ice core data sets only start to make any sense at all when you correlate them to solar data. This is why we can see 5000ppm CO2 during an ice age, because the solar activity was almost 4% less than today.

Mass is an intrinsic property - it exists regardless of gravitational field. Weight only exists if gravity is present.

If mass is present then so is gravity.

True. Mass creates gravity as far as we know.

The mass of the tree is transformed via chemical and physical reactions that turn various reactants into bark, leaves, the trunk etc. Co2, light, nutrients, water, ect. The mass of the tree is the sum of the input of these reactants. This is the law of mass conservation.

The weight of the tree is calculated by the earths gravitational force which is IIRC from physics class...something like 9.8m/s^2.

A person has the same mass on the earth and the moon. Think of this as the atoms which comprise your entire body, it doesnt change. However, your weight is less on the moon because the gravitational force on the moon is less than the earths 9.8m/s^2.

I've learned much in this thread. Thanks guys.

Yes - trivial amounts for objects of typical mass. It's been a while since I had to do those calcs back in college physics, but it takes a whole lotta mass to create any measurable gravity.

Take a brick with constant MASS up to Denver (where trees weigh less) and weigh it.

Better use an accurate device. I seem to recall that gravitational force is related to the square of the distance between the center of mass of two objects. That puts the change at about 0.05%. I'm sure the serious guys in the Reloading section consider that to be a huge difference.

Look up apparent mass.
Might not matter to reloaders but it makes a difference in accurate measurements.
People pay big bucks for a 0.02 grain resolution scale,
calibrate it @ 50 grams,
to weight 40 grains
