The motion of an object moving in a curved path is called curvilinear motion. Example: A stone thrown into the air at an angle.

Curvilinear Motion
Curvilinear motion refers to the movement of an object along a curved path. Unlike linear motion, where an object moves in a straight line, curvilinear motion involves movement in a curved or nonlinear path. This type of motion is commonly seen in various real-world scenarios, such as the motion of a car driving along a winding road or a satellite orbiting around a planet.

Key Points:
- Curvilinear motion can be described using parameters such as displacement, velocity, and acceleration.
- The path followed by an object in curvilinear motion can be represented by a curve or a series of connected curves.
- The velocity of an object in curvilinear motion is not constant and changes as the object moves along the curved path.
- Acceleration in curvilinear motion can be tangential, radial, or a combination of both, depending on the shape of the curve and the forces acting on the object.
- Curvilinear motion can be analyzed using mathematical equations and formulas derived from calculus and physics principles.
In conclusion, curvilinear motion is a common type of motion that involves movement along a curved path. Understanding the concepts and principles of curvilinear motion is essential in various fields, such as physics, engineering, and robotics, where the analysis and prediction of object movement are crucial.
