Projectile Motion
The following applet can be used to examine the motion of a projectile under the influence of gravity. Simply enter the initial height, velocity, acceleration due to gravity, and launch angle of the projectile and the applet will automatically draw the projectile's path and the horizontal distance traveled. Press the "Launch" button to animate the motion of the projectile. The initial height and launch angle can be changed by simply typing a new value, such as "1.2345", "pi/2", "sqrt(5)+cos(3)", etc. You may also change these values by using the up/down arrow keys or dragging the corresponding point on the graph. To move the center of the graph, simply drag any point to a new location. To label the xaxis in radians (i.e. multiples of pi), click on the graph and press "controlr". To switch back, simply press "controlr" again.
