A potter is shaping a bowl on a potter€™s 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 the diameter of the bowl is 12 cm?
(b) How long would it take for the potter€™s wheel to stop if the only torque acting on it is due to the potter€™s 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.
