Explain surface energy. Establish its relation with surface tension.

The SI unit of angular acceleration is

Circular motion: angular velocity | Angular acceleration | Uniform circular motion: radial acceleration

Circular motion: angular velocity| Angular acceleration| Uniform circular motion: radial acceleration

Angular Acceleration and Centripetal Acceleration

A disc of radius R rolls on a horizontal ground with linear acceleration a and angular acceleration alpha as shown in Fig. The magnitude of acceleration of point P as shown in the figure at an instant when its linear velocity is v and angular velocity is omega will be a

A disc rotates with constant angular velocity. Doesa point on its rim have a tangential acceleration or a radial acceleration ? Are these accelerations constant ? '

Name the rotational analogue of linear acceleration.

A point mass moves along a circle of radius R with a constant angular acceleration alpha . How much time is needed after motion begins for the radial acceleration of the point mass to be equal to its tangential acceleration ?
