+# Projectile Motion
+
+This is a 2D implementation of the physical formula for projectile motion.
+
+![img.png](img.png)
+
+$$ x(t) = x_0 + \frac{1}{2} a_x t^2 + v_{0x} t $$
+
+Also, during the shock with the ground, the projectile will lose some energy.
+This is simulated with a coefficient of restitution.
+
+Then, when not bouncing and only sliding on the ground, the projectile will lose energy due to friction.
+
+## Requirements
+
+- Java (6 to) 8 (max, recommended)
+- NetBeans (highly recommended)
+
+Java Applets have been dropped with Java 9. So you need an older versione to run this project.
+Java 8 is the preferred version. Until Java 6 should be ok.
+
+Problems running the project are expected, applets are deprecated and not supported by modern browsers.**
+
+This is a NetBeans Project. Using NetBeans isn't mandatory but recommended for the built-in applet runner.
+You can run the GrigliaApplet.java class with netbeans.
+
+[NetBeans Instructions](https://netbeans.apache.org/tutorial/main/kb/docs/java/javase-jdk8/)
+
+Alternatively, you can use IntellijJ IDEA with the [Applet runner plugin](https://plugins.jetbrains.com/plugin/16682-applet-runner) (not tested).
+
+## Installation and run
+
+Clone the repo:
+
+```bash
+git clone git@gitlab.com:stefanorossiti/projectiles.git
+```
+
+Run `AppletProiettile.java` with your preferred IDE (NetBeans is recommended) 
+using 
+java 8.
