Document Summary
Vt r) / dt (cid:224) a = d ( (cid:224) a = v + r (cid:224) a = 2r + r (cid:224) a c = 2r (cid:224) a c = v2/r centripetal acceleration will increase if tangential velocity increase or if the radius of rotation decreases. As the object moves through the fluid quicker, the fluid moves by the object faster the points of separation move forward on the object, and the fluid separates from the contours of the object closer to the front of the object(cid:224) at relatively high velocities, the fluid does not maintain a laminar flow (cid:224) separated flow (partially turbulent flow) fluid is unable to contour the shape of the object, and the boundary layer separates from the surface produces turbulence behind the object (is a low pressure region). Muscular strength depends on muscle size, fascicle arrangement, size of active motor units, multiple motor unit summation, temporal summation, the length tension relationship, fatigue.
