A potter is shaping a bowl on a potters wheel rotating at constant angular speed (Fig. 8-42). The friction force between her hands and the day is 1.5 N totals (a) How large is her torque on the wheel, if
(a) How large is her torque on the wheel, if the diameter of the bowl is 12 cm?
(b) How long would it take for the potters wheel to stop if the only torque acting on it is due to the potters hand? the initial angular velocity of the wheel is 1.6 rev/s, and the moment of inertia of the wheel and the bowl is 0.11 kg m2.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
