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

Vertical circular motion:

1. A body spins in a vertical circle in such a way that its motion at different points differs from the body's motion, which is assumed to be vertical circular motion.
2. Consider a mass m object wrapped in a stretchable string at one end and whirled in a vertical circle with radius d.
3. Because of the effect of the earth's gravitational force, the velocity and tension of the object vary in maximum magnitude from the lowest to the highest position.
4. As a result, the body's motion in a verticle circle is non-uniform.
