Question

Example of motion: Pedal of a bicycle in motion.
Type/ types of motion:_________________

Answer 1

A bicycle is defined as a vehicle that works on the basic principle of mechanics. We know that in a bicycle, there are two wheels that are connected to each that is rotated by means of pedaling. When we pedal, the wheels rotate by producing the forward motion to the bicycle.

Complete answer:
We know that when a person rides a bicycle, the force is applied to pedals as a result of which the chain over the pulley that is attached with pedals starts rotating. When the pedals start moving, the wheels attached to the pedals will also start moving.Therefore, we can say that the movement of the bicycle depends upon the combined movement of different parts of the bicycle.

The movement of different parts of a bicycle are given below:
-The wheel of a bicycle always exerts a rotatory motion.
-The chain of bicycles over the pulley exert a circular motion.
-The pedal of a bicycle with its arm exerts a circular motion.
-The movement of feet that is used for pedaling exerts a circular motion. This motion is also related to periodic motion.
-The movement of the rider on the bicycle exerts a multiple and Random motion.

Therefore, we can say the motion of the pedal of a bicycle will be circular motion.

Note: Every object in the universe always undergoes a vibratory motion. But at the macro level of operation, the value of vibration will be very low as compared to the other forces that act on the body. Therefore, for such cases, the vibrational motion will be neglected. Also, the motion in which the object undergoes a circular path is known as circular motion.
