Because wheel of cycle rotates in circular form when we ride the bicycle

Introduction:
The cycle of a wheel involves circular motion, and there are several reasons why this is the case. In this response, we will explore the key factors that contribute to the circular motion of a wheel.

1. Shape and Design:
The shape and design of the wheel play a crucial role in the circular motion it exhibits. A wheel is typically round and symmetric, with a central axle and a rim that encompasses the outer edge. This circular shape allows the wheel to rotate smoothly in a circular motion.

2. Axle and Bearings:
The axle is a central component of the wheel that helps facilitate its circular motion. It acts as a support for the wheel and allows it to rotate freely. Additionally, bearings are often used to reduce friction between the axle and the wheel, enabling smooth rotation in a circular path.

3. Forces and Torque:
When a force is applied to the wheel, it generates torque. Torque is the rotational force that causes an object to rotate. In the case of a wheel, the applied force creates a torque that causes the wheel to rotate around its axle in a circular motion.

4. Conservation of Angular Momentum:
The conservation of angular momentum is a fundamental principle in physics that explains why the cycle of a wheel follows a circular path. According to this principle, when a wheel is set in motion, its angular momentum remains constant unless acted upon by an external force. As a result, the wheel maintains its circular motion as long as no external forces, such as friction or an applied force, disturb its motion.

5. Centripetal Force:
Centripetal force is another factor that contributes to the circular motion of a wheel. It is the force acting towards the center of the circular path, keeping the object (in this case, the wheel) moving in a curved trajectory. In the case of a wheel, the centripetal force is generated by the friction between the wheel and the ground, providing the necessary force to keep the wheel moving in a circular motion.

Conclusion:
The cycle of a wheel is a result of various factors, including its shape, design, axle, bearings, forces, torque, conservation of angular momentum, and centripetal force. These factors work together to enable the wheel to rotate smoothly in a circular path, making it an essential component in many forms of transportation, machinery, and everyday life.
