The displacement vector Δ r → gives the shortest distance between any two points on the trajectory of a particle in two or three dimensions The velocity vector is tangent to the trajectory of the particle

Graphically, it is a vector from the origin of a chosen coordinate system to the point where the particle is located at a specific time Instantaneous velocity gives the speed and direction of a particle at a specific time on its trajectory in two or three dimensions, and is a vector in two and three dimensions

velocity vector — vector that gives the instantaneous speed and direction of a particle; tangent to the trajectory. displacement vector — vector from the initial position to a final position on a trajectory of a particle. trajectory — path of a projectile through the air. point where the particle — located at a specific time.
