Document Summary
Biomechanics: is there any interaction between different parts, yes, between muscle, tendon and bone, actually, the force of muscle is transferred to the bone via a tendon. Force: what do forces do, forces cause changes in velocity. The amount of acceleration produced is proportional to the amount of force (cid:38) (cid:118) F (cid:32)(cid:38) a const: what is the constant: (cid:38) F (cid:32)(cid:38) a m: the constant of proportionality relating force to acceleration is simply the mass of the object being accelerated: (cid:38) (cid:32) (cid:38) amf, this is newton"s second law. Newton"s second law: if a force acts on an object of mass. , it produces an acceleration, , of a(cid:38) m the object such that: (cid:38) (cid:32) F (cid:38) am m is the (inertial) mass of the object. Newton"s second law: if several forces act on an object, the. ,netf(cid:38) sum of the forces, called net force produces the resultant acceleration: (cid:38)
