A ballerina with an angular velocity of 1000°/s with her left hip in 90° flexion and knee fully extended, meaning that her foot is directly in front of her body. The distance from her axis of rotation to her foot is 0.95m. What is tangential velocity of her foot as she spins (in m/s)?
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.
