1)
La distancia recorrida es una magnitud escalar que se mide sobre la trayectoria. El desplazamiento es una magnitud vectorial que depende solo de la posición inicial y final del cuerpo y que es independiente de la trayectoria. 2)
El movimiento de proyectil, también conocido como movimiento parabólico, consiste en lanzar un cuerpo con una velocidad que forma un ángulo α con la horizontal. En la siguiente figura, puede ver una representación de la situación. Este movimiento es característico de los proyectiles, los objetos en movimiento se ven afectados solo por la gravedad. 3)
no tengo idea de esto lo siento 4)
El movimiento de velocidad constante, también conocido como movimiento rectilíneo uniforme (u.r.m.), es el que tiene velocidad constante, es decir, la trayectoria es una línea recta y la velocidad es constante. 5)
Un cuerpo se mueve con un movimiento de aceleración constante o un movimiento rectilíneo uniformemente acelerado (u.a.r.m) cuando su trayectoria es una línea recta y su aceleración es constante y diferente de 0. Esto implica que la velocidad aumenta o disminuye su magnitud de manera uniforme.
