Circular motion refers to the movement of an object along a circular path. This can occur at a constant speed, known as uniform circular motion, or with changing speed. The object experiences a continuous change in direction, which requires a force directed toward the center of the circle, called centripetal force. Examples include a car turning around a curve or a planet orbiting a star. In circular motion, the object's velocity is always tangent to the circle, while acceleration points inward. This inward acceleration is crucial for maintaining the circular path. Common examples of circular motion include a spinning top or a satellite orbiting the Earth. Understanding these principles helps explain various phenomena in physics and engineering.
