📖 1. Planar motions

🔑 Key Concepts & Definitions

• Planar motion: Movement confined to a plane, meaning all points of the moving object stay within a single flat surface during the motion.
• Examples of planar motions: Activities such as a car driving on a flat road, a person walking on a level ground, or a ball rolling on a horizontal surface. These are instances where the movement occurs within a two-dimensional plane.
• Characteristics of planar motions: The motion occurs in a single plane, and all points of the object share this same plane. The motion can be described using two-dimensional coordinates within that plane.

📝 Essential Points

• Planar motion is characterized by movement restricted to a plane, simplifying the analysis of the motion.
• Examples like a car on a flat road illustrate the concept of planar motion, emphasizing movement within a two-dimensional surface.
• The key feature of planar motions is that the entire movement takes place within a single plane, making it distinct from spatial (three-dimensional) motion.
