Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation:
refers to the value of the final position.
refers to the value of the initial position.
is the symbol used to represent displacement.
Average velocity is the displacement of an object, divided by the time it took to cover that distance.
Displacement is the straight line distance between the starting point and ending point of an object's motion.
Velocity is referred to as a vector quantity because it has both magnitude and direction.
