2-1 Position, Displacement, and Distance In describing an object’s motion, we should first talk about position – where is the object? A position is a vector because it has both a magnitude and a direction: it is some distance from a zero point (the point we call the origin) in a particular direction. With one-dimensional motion,

Example: Particle A is intially at the point (3, 4) and travels with velocity 9i – 2j m s-1. Particle B is intially at the point (6, 7) and travels with velocity 6i – 5j m s-1. Find the position vectors of A and B at time t. Show that the particles collide and find the time and position of collision.

Δx = xf − x0, where Δ x is displacement, x f is the final position, and x 0 is the initial position. We use the uppercase Greek letter delta (Δ) to mean “change in” whatever quantity follows it; thus, Δ x means change in position (final position less initial position).
A position is a vector because it has both a magnitude and a direction: it is some distance from a zero point (the point we call the origin) in a particular direction. With one-dimensional motion, we can define a straight line along which the object moves.
Measurement from your initial position to your final position is distance traveled, and the measurement of the total length of your path from the starting position to the final position is displacement.
