Hi Following on from my last post on the difference between CoM and CoG is this presentation looking at Centre of Mass, Centre of Pressure and Centre of Force, The Three C's. I think that these three are in many ways very similar in concept and do well to be understood and studied together. Here is the 1st Part Centre of Mass  I think you'll find this more relevant to Podiatric Biomechanics that perhaps the previous blogs have been. Enjoy!

Hi to anyone who's been following It been a while since my last post, sorry about that I've had a few projects to get on with lately, so  I thought I'd give younthis little snippet. What's the difference between Centre of Mass and Centre of Gravity? We often see CoM and CoG usqed interchangably as if they were the same thing but are they? Simply put No! Remember that mass is not dependent on gravity, a body has mass even when not in a gravitational field and the positionnof CoM is constant whatever the variation in the gravitation field. Centre of Mass is the theoretic centre of the distribution of all the particles of mass in a body. That is, the point where the sum of all the distrubuted particles would equal zero. It is the point where, if a force is applied the body would move in a straight line without any rotation of the body. The CoM is not necessarily found within the mass of the body of interest, in a hoop or a football the COM is in the centre of the spa
