A body moving only along one direction that is either along the x-axis are long y-axis is called as a one-dimensional motion.

If a body has to move along the horizontal direction, there may be need of some force that is acting along the direction of motion so that it is having some acceleration in the direction.

A body can also move along two directions, when two forces are acting on the body into different directions simultaneously and a typical example for this kind of motion is a projectile motion.

A physical quantity who has both magnitude and direction and which satisfies the rules of the vectors is called as vector.
