Non uniform circular motion is the motion of an object along a circular path where the speed of the object is not constant. This means that the object is accelerating, changing its velocity, and possibly its direction, as it moves along the circular path.
In uniform circular motion, the speed of the object remains constant, while in non uniform circular motion, the speed changes. Additionally, in uniform circular motion, the acceleration is always directed towards the center of the circle, whereas in non uniform circular motion, the acceleration may not be directed towards the center.
Friction is a force that opposes the motion of an object. In non uniform circular motion, friction can affect the speed, direction, and acceleration of the object. It can also cause the object to slow down or speed up, depending on its direction and magnitude.
Centripetal force is the force that keeps an object moving along a circular path. In non uniform circular motion, the centripetal force may change as the speed and direction of the object change. If the centripetal force is not balanced, the object will not be able to maintain its circular motion and will either slow down or deviate from its path.
Some examples of non uniform circular motion include a car driving around a curved road, a satellite orbiting the Earth, and a rollercoaster moving along its track. In each of these examples, the speed and direction of the object change as it moves along a circular path, making it non uniform circular motion.
