Displacement vector in a plane

The displacement vector of a moving particle, between two instants t1 and t2, is a vector that joins the positions of the particle at t1 and t2, The displacement vector between t1 and t2 is: ∆r ̂ = r ̂ 2 - r ̂ 1 ‖∆r ̂ ‖ is the shortest distance between A and B. (AB) ̂ is the traveled distance between A and B. Generally, the traveled distance is different from the magnitude of the displacement vector: ‖∆r ̂ ‖ ≠ (AB) ̂ ‖∆r ̂ ‖ = (AB) ̂ only in rectilinear motion in one direction. After finishing the explanation of the displacement vector, we are going to solve an exercise about this vector. You can watch: 1) Position vector in a plane :    • Position vector in a plane   2) Equation of trajectory in a plane :    • Equation of trajectory in a plane   3) Average and instantaneous velocity vectors :    • Average and instantaneous velocity vectors   4) Average and instantaneous acceleration vectors :    • Average and instantaneous velocity vectors   5) tangential and normal acceleration :    • Tangential and normal acceleration
