linear motion

**linear motion**

Linear motion refers to movement in a straight line, where an object travels along a path without changing direction. It is a fundamental concept in physics and engineering, describing how objects move from one point to another in a single dimension. Common examples of linear motion include vehicles driving on a straight road, a train on tracks, or a piston moving within a cylinder. This type of motion is characterized by parameters such as displacement, velocity, acceleration, and time, making it essential for understanding mechanics and designing mechanical systems.
