(A) What is the tangential acceleration of a bug on the rim of a 10.0 in diameter disk if the disk accelerates uniformly from rest to an angular speed of 78.0 rev/min in 3.00s? (B) When the disk is at its final speed, what is the tangential velocity of the bug? One second after the bug starts from rest, what are its (C) tangential acceleration, (D) centripetal acceleration (E) total acceleration?
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.
