what is circular uniform motion explain with example
Answers
Step by Step Explanation of Answer ✿
The term “Uniform circular motion” is the kind of motion of an object in a circle at a constant speed. With uniform circular motion, as an object moves in a particular circle, the direction of it is constantly changing. Herein, in all instances, the object is moving tangent to the circle .
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch .
An example for circular uniform motion
is upside ( an attachment of photo is upside )
A body is said to be in a circular motion if it is fixed to a point and covers distance along the circumference of the circle formed by the radius of the strong connecting the body and the axis of rotation.
Explanation:
Example :
if a ball attached to a rope on one end, is rotated keeping the other end of rope fixed...then it is undergoing circular motion.
Moreover...a body undergoing circular motion can rotate with a uniform speed or a non uniform speed .
In case of uniform speed it is termed as "uniform circular motion ".
Also, we know that acceleration comes into play when there us a change in velocity.
Here in the case of circular motion,, even if the body rotates with a uniform speed...then also it will be an accelerated motion. Why is this so??
Well, the answer is simple. The magnitude of the velocity (speed only) remains constant but in circular motion, the direction constantly changes at every instant (because the rope is fixed at a point) . Since velocity is a vector quantity, the velocity keeps on changing along with the change in direction.
Hence a uniform circular motion is an accelerated motion.
