* An arrow from the origin to the final position car, labeled $S$.
* A double-headed arrow between the initial and final positions, labeled $\Delta S$, indicating displacement. All arrows point to the right, suggesting positive direction.
**Right Diagram:**
* Type: Schematic illustration showing positions along a straight line.
* Main Elements:
* A horizontal line representing the road or trajectory.
* A person riding a motorcycle is shown near the left end of the road, close to the "0" sign.
* Five vertical poles with square signs are placed along the road. The signs are labeled from left to right with numbers: 0, 10, 20, 30, 40. These numbers likely represent positions or distances.

MOVIMIENTO RECTILÍNEO UNIFORME (M.R.U)
**Definition:**
Es aquel movimiento que experimenta un móvil al desplazarse sobre una trayectoria rectilínea con velocidad constante.
**Diagram Description:**
* **Type:** Simple physics diagram illustrating uniform linear motion.
* **Main Elements:**
* A horizontal line representing a straight path or surface (possibly ground), with a textured fill indicating texture.
* A circular object (yellow with a grey outline) is shown at the left end of the horizontal path, with horizontal lines behind it suggesting motion.
* An arrow labeled "V" is placed above and to the left of the object, pointing to the right, representing velocity.
* A curved arrow originating above the object at the left and extending to the right along the implied path is labeled "t" (presumably representing time or duration). The arrow points to the right.
* A horizontal line segment below the path, marked by vertical segments at its ends, is labeled "d" (representing distance or displacement). The segment extends below the length of the illustrated motion.

* **Title:** Movimiento Rectilíneo Uniforme
* **Labels along the line:**
* 0 metros
* 0 segundos
* 100 metros
* 20 segundos
* **Mathematical Formula and Calculation:**
V = d/t = 100 m / 20 s = 5 m/s
**Chart/Diagram Description:**
* **Type:** Illustration and diagram representing motion.
* **Main Elements:**
* **Illustration:** A person running, shown in three positions along a horizontal path. The leftmost two positions are faded, suggesting earlier moments, while the rightmost position is clear, representing the final state shown.
* **Line:** A horizontal line segment with an arrow pointing to the right, indicating the direction of motion.
* **Labels:** Text labels are placed below the line at its left end and right end. The left end is labeled "0 metros" and "0 segundos". The right end is labeled "100 metros" and "20 segundos". A vertical tick mark is present above the left end label.
* **Formula:** Below the line, the formula for velocity (V) is shown as V = d/t. The values from the diagram are substituted into the formula: 100 m for 'd' and 20 s for 't'. The result of the calculation is shown as 5 m/s.
* **Relative Position and Direction:** The runner is depicted moving from left to right, consistent with the arrow on the horizontal line. The initial position (0 meters, 0 seconds) is on the left, and the final position (100 meters, 20 seconds) is on the right. The formula and calculation are shown below the motion diagram.

¡Hola, futuros científicos! Hoy vamos a descubrir el Movimiento Rectilíneo Uniforme, o M.R.U. ¡Es más fácil de lo que suena! ¿Alguna vez has visto algo moverse en línea recta sin cambiar su velocidad? ¡Eso es exactamente el M.R.U.!
Ahora vamos a entender qué significa 'rectilíneo'. Rectilíneo significa que el objeto se mueve en una línea recta. ¡Su camino no se curva ni cambia de dirección! Aquí podemos ver la diferencia: una trayectoria rectilínea es una línea recta, mientras que las trayectorias no rectilíneas pueden ser curvas o en zigzag.
Ahora entendamos qué significa 'uniforme'. Uniforme significa que su velocidad es constante. Esto quiere decir que recorre la misma distancia en el mismo tiempo, ¡siempre! Observa este ejemplo: si el objeto tarda 1 segundo en ir de 0 a 10 metros, también tardará exactamente 1 segundo en ir de 10 a 20 metros. Su velocidad no cambia nunca.
Ahora veamos las fórmulas del M.R.U. Las tres fórmulas principales son: distancia igual a velocidad por tiempo, velocidad igual a distancia dividida por tiempo, y tiempo igual a distancia dividida por velocidad. Este triángulo mnemotécnico te ayuda a recordarlas fácilmente. Si tapas la variable que quieres calcular, las otras dos te muestran la fórmula. ¡Es tu superpoder para resolver problemas de M.R.U.!
Veamos un ejemplo práctico. Un corredor se mueve en línea recta. Empieza en 0 metros cuando el tiempo es 0 segundos. Llega a 100 metros cuando el tiempo es 20 segundos. ¿Cuál es su velocidad? Usamos la fórmula v igual a d dividido por t. Sustituimos los valores: d igual a 100 metros, t igual a 20 segundos. El resultado es 5 metros por segundo. Como es M.R.U., ¡siempre correrá a 5 metros por segundo!
