Center of Mass and Center of Gravity (basic concepts of biomechanics) Physiotherapy class linked in :   / adhip-nadkarni-5b45241a6   twitter :   / adhip_nadkarni   summary of the video with the time for reference: 1.Gravity -Downward pull of gravity on human body and objects -Constant -Always acts on the body 2.Center of Gravity -Point of application of gravity on object or its center of mass 3.Center of mass -Hypothetical segment where all the mass of object/segment appears to be concentrated -In human body it is anterior to sacral vertebra -changes with position and changes with motion -midpoint in symmetrical objects and might not be at the midpoint in asymmetrical objects 3.Line of Gravity -Gravitational Vector -Acts vertically downward #centreofmass #centreofgravity
