Curvilinear motion refers to the motion of an object along a curved path. Unlike linear motion, which occurs in a straight line, curvilinear motion involves changing directions while the object moves, resulting in a trajectory that is not straight. Some key characteristics of curvilinear motion include: 1. **Trajectory**: The path taken by the object is curved, which can be circular, elliptical, or any other non-linear shape.

The laws of motion, formulated by Sir Isaac Newton in the 17th century, are three fundamental principles that describe the relationship between the motion of an object and the forces acting upon it. These laws are foundational to classical mechanics and provide a framework for understanding how objects move.

Proper motion is the apparent angular motion of a star or other celestial object across the sky, as observed from a specific location over time. It is measured in arcseconds per year and represents the object's movement perpendicular to the line of sight from the observer. Proper motion is a consequence of the object's actual motion through space relative to the observer, combined with the effects of the observer's position (like being on Earth) and the object's distance.
