Circular motion is the movement of an object along a circular path, or the circumference of a circle, while maintaining a constant distance (the radius) from a central point. A key aspect is that the object's direction . Two types of circular motion : 1.Uniform circular motion: The object moves at a constant speed. 2.Non-uniform circular motion: The object's speed varies as it moves. Examples: A satellite orbiting the Earth. A car driving around a round turn at a constant speed (uniform). A Ferris wheel (uniform). A ball on a string being swung in a circle (can be uniform or non-uniform). f velocity is continuously changing, even if its speed is constant.
