The bus's wheels have a radius 26 cm. The bus starts at rest and accelerates at a constant speed until it reaches an angular speed of 10.4 rev/s. During this period, the bus moved 100 m. How many revolutions does the wheel go through?
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.
