A devious classmate swings a sharp pencil at the end of some thread capable of withstanding only 10 N of force. Swinging a 20 g pencil in a horizontal, 50 cm radius circle, at what speed will the thread break and possibly strike down an innocent classmate in the prime of life? Show your work, including all of those items expected in force problem solving.
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.
