The CGS unit for measuring the viscosity of a liquid is the poise (P): 1 P 1 g/(s cm). The SI unit for viscosity is the kg/(s m). The viscosity of water at 0 C is 1.78 103 kg/(s m). Express this viscosity in poise.
Circular Motion Circular motion ● An object moving in a circle must have a force acting on it otherwise itwould just move in a straight line. ● The force points to the center. ● Centripetal force and centripetal acceleration always point to the center mv2 ○ Fc = m a c= r Δv v(final− v(initial) ○ a = Δt = Δt ● Acceleration i produced if ○ Speed changes but movement remains ina constant direction ○ Velocity direction changes but speed is constant ● Variables ○ Something on string = F
