Document Summary
Variable acceleration constant accel. a = ac v = d s d t v = v 0 + ac t - t0 a = d v d t. = d 2 s d 2 t s = s0 + v 0 t -t0 + ac. 2 + 2 ac s -s0 r, , z coordinates ar = r r vr = r. + 2 r v z = z az = z v dv = a ds. Constant = c ab = aa + ab/a vb = va + vb/a. For any point p in circular motion s = r. Relative motion-translating axes vb = va + vb/a(pin) Axis vb = va + x rb/a + (vb/a)rel ab = aa + x rb/a - 2 rb/a {<= x xr} ab = aa + ab/a(pin) Mg = ig mp = (mk)p. Power and efficiency dt = f v. V = vg + ve, where vg = wy, ve = + 1.
