Uniform Circular Motion
What is Difference between Uniform Circular Motion and Non-Uniform Circular Motion?
The only key difference between uniform and non-uniform circular motion is the speed of the motion, i.e., in uniform circular motion speed of the object performing is constant whereas, in a non-uniform circular motion, the speed is varying.
Why Uniform Circular Motion is called Accelerated Motion?
In uniform circular motion speed is constant but due to the changing direction of the motion velocity is always changing thus there is always a change in velocity i.e., there is always an acceleration acting on the object.
What is the Centripetal Force?
Due to the always present acceleration, there is a force acting on the body in the direction of the center of the circular path which is called centripetal force.
What are Examples of Uniform Circular Motion?
The motion of electrons in Bohr’s atomic model, constant revolutions of a ceiling fan, constant spinning of CD and DVD in the player, and motion of a Ferris wheel are some examples of uniform circular motion.
Can an Object be in a Uniform Circular Motion if its Speed is Changing?
No, as uniform circular motion is defined for the constant speed of the object if speed started changing it becomes non-uniform circular motion.
Uniform Circular Motion
Uniform Circular Motion as the name suggests, is the motion of a moving object with constant speed in a circular path. As we know, motion in a plane only has two coordinates, either x, and y, y and z, or z and x. Except for Projectile motion, circular motion is also an example of motion in a 2-D plane.
In a uniform circular motion, the object moves with constant speed but not with constant velocity as the direction of the motion is due to the circular path always changing. From the motion of electrons in Bohr’s Atomic model to the motion of the hands of an analog clock, we can see Uniform Circular Motion around us.
In this article, we will learn about the details of Uniform Circular Motion i.e., formulas related to uniform circular motion, examples, and the equation of motion of the uniform circular motion.
