Tricks to Move Large Rocks by a Single Person | Hunker
Attach one end to an immovable object like a tree or truck. The other should be fitted with nylon or canvas straps around the rock to be moved. By ratcheting the hoist, a single person can move the rock one small bit at a time using much less human force than if he were to walk up and simply try to drag the thing by hand.

What's as dense as lead but non magnetic? This odd rock I ...
It looks like a chert nodule, which is very possible in carbonate territory. If this is chert, a chunk the size of a 2 liter bottle should weigh about 11.5 pounds - that seems the right ballpark for your rock. If it was really the density of lead, a 2-liter sized chunk would weigh almost 70 pounds. So I vote for chert.

How to Calculate Weight of a Rock | Hunker
If you don't know what kind of rock you're measuring, use the following figures (these are the average specific gravities of most rocks): 2.7 g/cm3 (2,700 kg/m3) or .0975 lbs/in3 (168.55 lbs/ft3). Step 3 Multiply the volume of the rock by its specific gravity. The resulting number is the weight of the rock.

Q & A: Heavy and Light - Both Fall the Same | Department ...
In the absence of air friction both heavy and light objects will reach the ground at the same time. Galileo deduced this by devising clever experiments with balls rolling down inclined planes. Newton gave it his blessing by observing that a = F/M, i.e. the acceleration of an object is proportional to the force, F, on it divided by its mass, M.

NCPTT | Calculating the Weight of Stone
First off, locate the type of stone you are using on the chart. Next multiply the cubic feet you obtained from using step one to the number in the minimum lbs/ft3 column. That number is approximately the minimum weight of the stone. You then do the same in the maximum lbs/ft3 column to obtain the maximum weight of the stone.
