Consider the clock in Figure 8.17. Calculate the magnitude and sign of the torque due to gravity
Question:
Consider the clock in Figure 8.17. Calculate the magnitude and sign of the torque due to gravity on the hour hand of the clock at 4 o???clock. Assume the hand has a mass of 15 kg, a length of 1.5 m, and the mass is uniformly distributed.

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.
