Linear motion refers to the movement of an object along a straight path. This type of motion can be described by its position, velocity, and acceleration. In linear motion, the object moves in one dimension, meaning it can only go forward or backward without changing direction. In physics, linear motion is often analyzed using equations that relate distance, time, and speed. For example, the formula distance = speed × time helps calculate how far an object travels in a given time at a constant speed. Understanding linear motion is essential in various fields, including engineering and transportation.
