Linear velocity, angular velocity

Linear velocity is nothing more than the velocity of an object in a straight line, whereas angular velocity is how much an objects spins, rotates, or turns.

Problems Linear and Angular Velocity

Clock Hands: The angular velocity is independent of the clock size, however for larger clocks the linear velocity of the pointers at the end of the hands will be greater. The second hand goes through 2π radians in 1 min, or 2π radian/60 seconds, so ω = π/30 rad.
