The world’s narrowest street, which is located in a small Italian village, is only 43 cm wide. Suppose a fish with a mass of 1.8 kg is hung from a string attached to a stick. The stick, slightly longer than the street is wide, is placed horizontally across the narrow street with each end resting on a windowsill. The fish hangs a horizontal distance of 7.0 cm from the windowsill on the right. If the axis of rotation for the stick is taken to be the end farthest from the fish, what is the magnitude of the torque produced by the fish? Assume the stick has negligible mass.
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
