| Pirates Applet IMPORTANT: This is a new window. To return to where you were please close this window. With this game you can learn about ballistic motion by controlling the cannon on an old British navy sailing ship which is hunting down pirates. How Do I Use It? To fire your cannon press the "fire" button in the top left corner of the screen. You can pause the ball at any time by pressing the "stop" button. When the ball has landed press "reset" so that you may fire again. Before you fire the cannon you may choose the angle and power with which it will fire using the settings in the top middle of the screen. Remember that only angles between 0 and 89 will fire forwards. You may also change the strength of gravity if you like. Things to Try Try to hit the pirate ship using as few shots as possible. Experiment with one factor at a time. For example, try to hit the ship by changing only the angle of the cannon and leaving the firing speed the same. Remember that a 45 degree angle will give you the most distance. For a challenge try hitting the ship only using angles above 45 degrees. Change the value of G from 10 to 26. This is approximatly the strength of gravity on the surface of Jupiter. |
