Circular is an adjective that describes something that is round or shaped like a circle. A circle is a simple closed shape in Euclidean geometry, being the set of all points in a plane that are at a given distance from a given point, the centre. The distance between any point on the circle and the centre is called the radius. Circles are fundamental in geometry and have numerous applications in various fields, including mathematics, physics, engineering, and art.

The circumference of a circle is the distance around it, while the area is the region enclosed by the circle. The formulas for the circumference and area of a circle are derived from the mathematical constant pi (π), which is the ratio of a circle's circumference to its diameter. The diameter is a straight line segment that passes through the centre of the circle and whose endpoints lie on the circle.

Circular motion refers to the movement of an object along the circumference of a circle. This concept is crucial in physics, particularly in the study of rotational dynamics and kinematics. Circular motion can be uniform, where the object moves at a constant speed, or non-uniform, where the speed varies.

In art and design, circles are often used to create balance, harmony, and visual interest. They can be found in various forms, such as wheels, gears, and patterns, and are used in logos, icons, and other graphical elements. The circular shape is also prevalent in nature, seen in the form of wheels, rings, and circular patterns in flowers and other natural structures.

The study of circles and circular motion is a fundamental aspect of geometry and physics, with applications in numerous fields. Understanding the properties and behavior of circles is essential for solving problems in these disciplines and for designing and analyzing systems that involve circular shapes and motion.
