La siguiente imagen muestra el recorrido que hace Gustavo para llegar desde su casa(punto A) hasta la casa de su amigo (punto F). Las medidas están en metros. a) Si Gustavo sigue el camino indicado en la imagen (f-g-h-i-j), ¿Cuántos metros recorre hasta la casa de su amigo? b) ¿Cuántos metros se desplazó Gustavo? (Use teorema de Pitágoras) *

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
