Motion is defined as the change in the position of an object over time relative to a reference point or frame of reference. It is a fundamental characteristic of all matter, meaning everything that has mass can be in motion

. In physics, motion is described by how an object's position changes with time, and it can be categorized into different types:

• Linear (straight) motion: movement along a straight line, such as a car driving on a straight road or an apple falling from a tree.
• Circular motion: movement along a curved path forming a circle, like the blades of a fan or a merry-go-round.
• Oscillatory motion: back-and-forth movement from a fixed point, like a pendulum or a child on a swing

Motion occurs due to forces acting on objects, and its study is divided into branches such as kinematics (motion without forces), dynamics (motion with forces), and mechanics (motion, forces, and energy)

. Newton's laws of motion are foundational in explaining how objects move and respond to forces: an object remains at rest or in uniform motion unless acted upon by an external force; force equals mass times acceleration (F=ma); and every action has an equal and opposite reaction

. In summary, motion is the process of an object changing its position over time, influenced by forces, and observable in various forms like straight, circular, or oscillatory movements
