Certainly, vertico/lateral stability will be improved but the centre of mass will remain in the same locus.

Centre of mass or centre of gravity?

The center of gravity of a body is a point where the weight of the body acts and the total gravitational torque on the body is zero.

The center of mass of a body is the point which behaves as if all the mass of the body is concentrated there. Thus, if a force acts at this point, the body will accelerate but will not rotate.

I think it's the CoM that lowers, not the CoG.

From being a very active participant on the forum 20 years ago, I now visit only infrequently, which is why I have not heretofore noticed the above.

These definitions essentially are correct but a centre of mass is a static entity whereas CofG is a dynamic element subject to Newtonian and Galileic laws of motion.

And Bob is right to rue the paucity of general mathematical prowess. However, perhaps this is not surprising since I understand that four out of three people are not good with maths.

I send yuletide greetings.
