Which of the following describes how far and in which direction an object or a person is relative to the starting point?
a.Distance
b.Displacement
c.Speed
d.Velocity
-Displacement is the length and direction that an object has moved from its starting point.
Displacement (symbolized d or s ), also called length or distance, is a one-dimensional quantity representing the separation between two defined points.
EXAMPLE OF DISPLACEMENT
If an object moves relative to a reference frame—for example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplane—then the object's position changes. This change in position is known as displacement.
