Document Summary
Moments: torque=moment= the turning effect of force, bw= and opposite to grf, external=cw. If you are curled up, smaller mass moment= velocity is bigger: this makes sense because inertia is the resistance to, acceleration change, acceleration is dp to force, acceleration is ip to mass, f=ma. Increase the force with the same mass= increase acceleration: same force with an increased mass= decrease acceleration, aka more force is needed to accelerate larger mass to the same extent as a smaller mass. Not: ex: you push on a wall, the wall pushes back on you with equal force, but while you will not move the wall, the wall may move you. Jrfs: compressive/distraction forces= strain ct, joints encounter forces from contractions, gravity, externals, friction, passive, etc. that then create a jrf as a resultant (net sum) of all those forces that act on it to keep.
