Fórmulas de Movimiento Rectilíneo

El movimiento rectilíneo uniforme (MRU) es el más sencillo: la velocidad es constante. Su fórmula es x = x₀ + v·t, donde x es la posición final, x₀ la inicial, v la velocidad y t el tiempo.

Para el movimiento rectilíneo uniformemente acelerado (MRUA) necesitas dos fórmulas clave. La primera es v = v₀ + a·t para calcular la velocidad final. La segunda es x = x₀ + v₀·t + ½at² para la posición final.

Aquí v₀ es la velocidad inicial, v la final, a la aceleración y t el tiempo. Recuerda que si el objeto está en caída libre, la aceleración a se convierte en g = -9,8 m/s².

¡Ojo! En caída libre siempre usa g = -9,8 m/s² como aceleración, no olvides el signo negativo.

Fórmulas de Movimiento Circular

El movimiento circular uniforme (MCU) funciona igual que el MRU pero con ángulos. La fórmula básica es φ = φ₀ + ω·t, donde φ es el ángulo recorrido, φ₀ el inicial, ω la velocidad angular y t el tiempo.

Para el movimiento circular uniformemente acelerado (MCUA) tienes ω = ω₀ + α·t y φ = φ₀ + ω₀·t + ½αt². Aquí α es la aceleración angular.

Para convertir magnitudes angulares a lineales usa: s = φ·R, v = ω·R y a = α·R, donde R es el radio. También necesitarás ω = 2πf, f = 1/T y a = v²/R para la aceleración centrípeta.

Conversión clave: Si te dan ω en rpm, multiplica por 2π/60 para pasarlo a rad/s.

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.
