define linear dislplacement?

Linear displacement is the change in position of an object in a straight line from its initial position to its final position. It is a vector quantity that is measured in units of length, such as meters or feet.

Linear displacement is the distance between the initial and final positions of an object along a straight line. It is a vector quantity, which means that it has both magnitude (the distance) and direction (the direction of the straight line). The magnitude of the linear displacement is the length of the straight line segment connecting the initial and final positions, and the direction is the angle between the straight line segment and a reference axis.

Linear displacement is often used to describe the motion of objects in a straight line. For example, if an object moves from point A to point B along a straight line, its linear displacement is the distance between points A and B. The direction of the linear displacement is the direction from point A to point B.

Linear displacement is a fundamental concept in physics and is used in many different applications, such as kinematics, dynamics, and mechanics.
