Pressing the X in the lower right will clear all the graphs.

Click to "throw" the ball & see a graph of the position or velocity as a function of time.

Click the "reset time" button after each "throw".

Drag the "t" point to trace the graph (may be hidden under time label).

Questions

1. Watch the flight of the ball. Does the ball move at a constant speed or changing speed?

2. How much time does the ball spend in the air?

3. Trace by dragging "t" to get the maximum height of the ball. What is the velocity of the ball at the top?

4. Does the ball loses half of its velocity by the time it gets half way to the top?

5. Where is the x-intercept for the velocity graph? What is happening with the ball at this time?
