Question

write about the Non-uniform circular motion: ​

Answer 1

Answer:

The non-uniform circular motion, also called uniformly accelerated circular motion is motion with a circular trajectory in which the angular acceleration is constant.

Answer 2

$\huge\bf{\underline{\underline{Answer : -}}}$

When a fan is switched ON or OFF, the speeds of particles of the fan go on increasing or decreasing for some time, however their directions are always tangential to their circular trajectories.

During this time, it is a non-uniform circular motion. As the velocity is still tangential, the centripetal or radial acceleration ā_rar is still there. However, for non-uniform circular motion, the magnitude of ā_r ar is not constant
