Curvilinear motion refers to the movement of an object along a curved path. This type of motion can occur in two or three dimensions and is characterized by changes in direction, which can be caused by forces acting on the object. Examples include the trajectory of a thrown ball or the path of a car turning around a bend. In curvilinear motion, the object's velocity and acceleration can vary in both magnitude and direction. The analysis of this motion often involves concepts from physics, such as Newton's laws of motion and centripetal acceleration, which help explain how forces influence the object's path.
