[b]Water Cannon Simulator[/b] This applet allows you to manipulate the angle (direction) and strength (magnitude) of a water cannon. You can also change the force of gravity to see what affect it has.
1. What angle or angles lead to the water traveling the farthest horizontally? The shortest? 2. What angle or angles lead to the water traveling the highest? The lowest? 3. Gravity initially is set to a negative value, showing that it's a force pulling objects [b]down[/b]. What happens if you give gravity a positive value? Can you think of a real-world situation that would behave in a similar manner?
