⚔️🔬 Science 🔬⚔️ The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred, Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us ...
CIRCULAR MOTION
Physics deals with the various types of motions.
Moment of the partical in particular manner decide the motion of partical.
Motion is the change in position of an object with respect to its surrounding in a given interval of time.
The Circular motion is a special case of linear or translation motion.
Definition of Circular Motion
Circular motion is a movement of an object along the circumference of a circle. (rotation along a circular path.)
Types of Circular Motion
two types of circular motion
- Uniform circular motion : " The motion of particle along the circumference of circle with constant speed". Hence magnitude of angular velocity is constant. U.C.M can defined as periodic motion of a particle moving along circumference of a circle with constant angular speed. E.g. motion of earth around the sun. Motion of the moon around the earth.
- Nonuniform circular motion : " The motion of particle along the circumference of circle with different angular speed".
Most of the people play with the yo-yo, we enjoy with yo-yo by revolving, to-fro movie......etc but we just play and can't find the reason behind this. The string of the yo-yo plays and important role in this game. Some force applied to the string and some force or agents force create by string.
String create the for but why????
We applied force on the string but only one directional force can stable the yo-yo ????
The reason behind this, yo-yo string accept the external force and which provide by us, this force acting on yo-yo and string act as radius due to which some agents force product outward directional force and maintain the constant yo-yo.
Similarly, some force act on circular moving particle is known as centrifugal and centripetal force. This two force perform lead role in constant motion of circular moving particle.
Centripetal force and Centrifugal force :
"This is a force acting on particle performing Circular motion"
Centripetal force :
"The Force acting on particle performing Circular motion , which is directed towards the center and acts along radius is called Centripetal force".
Expression,Formula of centripetal force :

| *centripetal force formula* |
Centrifugal force :
"The Force acting on particle performing Circular motion , which is directed away from the center and acts along radius is called Centrifugal force ".
In uniform circular motion centrifugal force is a pseudo force.
In uniform circular motion centrifugal force is a pseudo force.
