Question

What is a vertical circular motion? Show that the motion of an object revolving in a vertical circle is non uniform in motion.

Answer 1

A body revolves in vertical circle such that its motion at different points is different then the motion of the body is said to be vertical circular motion.

consider an object of mass tied at one end of a mass m tied at one end of an int extensible string and whirled in a vertical radius of radius r. due to influence of earth's gravitational field, velocity and tension of the body vary in magnitude from maximum at bottom point to minimum at the top (highest) point. Hence the motion of body in a vertical circle is non-uniform circular motion.
