Position: Motion of any object is defined by its position with respect to the observer. Position is the location of the object. If object changes its position with the passage of time, it is said to be in motion. Reference point: It is the point from which the location of object is measured. It is often called as origin. Any object can be located only with the help of reference point and its direction. Example: Suppose a person changes its position with respect to a tree(a reference point) with passage of time. In this example, person is an object and tree is a reference point. Direction is also necessary to locate an object. Vectors & Scalar Vector is a quantity which have both magnitude and direction. Examples: Force, position etc. Scalar is quantity with which direction is not associated. Examples: Temperature, mass etc. Distance & Displacement Distance is the actual path travelled by an object from its initial position to final position. It is a scalar quantity. Displacement is the shortest straight line path between initial and final position. If the initial and final points are same then displacement will be zero. Distance depends on path but displacement does not. Distance is always greater than or equal to displacement. They are equal only in straight line motion without taking U- turn.
