Non-uniform circular motion is a type of motion in which an object moves along a circular path at varying speeds. This means that the object is not moving at a constant speed around the circle, but rather its velocity changes as it moves along the path.
In uniform circular motion, the object moves at a constant speed around the circle, meaning its velocity remains constant. Non-uniform circular motion, on the other hand, involves a changing velocity and thus a changing speed as the object moves along the circular path.
The acceleration in non-uniform circular motion is the change in velocity over time. Since the velocity is constantly changing in this type of motion, the acceleration is not constant, and its direction is always tangent to the circular path.
Non-uniform circular motion can be caused by a variety of factors, including an unbalanced force acting on the object, changes in the direction of the velocity, or changes in the radius of the circular path.
Centripetal force is the force that keeps an object moving in a circular path. In non-uniform circular motion, this force is also constantly changing, as it is always directed towards the center of the circle and its magnitude is dependent on the object's velocity and mass.
