Cinemática: Los Dos Movimientos Básicos

¿Te has preguntado alguna vez cómo calcular la velocidad de un coche o predecir dónde estará un objeto en movimiento? La cinemática te da las herramientas para hacerlo.

Existen dos tipos principales de movimiento: el Movimiento Rectilíneo Uniforme (MRU) y el Movimiento Rectilíneo Uniformemente Acelerado (MRUA). En el MRU, un objeto se mueve en línea recta a velocidad constante, como un tren en una vía recta. La fórmula básica es V = e/t, donde la velocidad es igual al espacio recorrido dividido por el tiempo.

Para calcular la posición de un objeto en MRU usas S = S₀ + V·t. Esto significa que la posición final es la posición inicial más el producto de la velocidad por el tiempo transcurrido.

El MRUA es diferente porque la velocidad cambia constantemente debido a una aceleración constante. Piensa en un coche que frena o acelera: su velocidad no es la misma todo el tiempo. Las fórmulas clave son V = V₀ + a·t para la velocidad y S = S₀ + V₀·t + ½·a·t² para la posición.

Truco importante: En el MRU la aceleración es cero a=0a=0, mientras que en el MRUA la aceleración es constante pero distinta de cero.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
