A small mass M attached to a string slides in a circle (x) on a frictionless horizontal table, with the force F providing the necessary tension (see figure). The force is then increased slowly and then maintained constant when M travels around in circle (y). The radius of circle (x) is twice the rádius of circle (y). a M's angular velocity at x is half that at y. BM's kinetic energy at x is half that at y. true equal to trun false greater than a M's angular momentum at y is ... that at x. St Answer Incorrect. Tries 2/12 Previous Tries BM's moment of inertia at y is one quarter that at x. e M's linear velocity at y is twice that at x.

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.
