The first part of this exercise allows students to change various parameters controlling the motion of a bouncing golf ball. Each parameter can be easily adjusted using a slide-bar. Repeated experimental drops can thus be performed in rapid succession, so that changes in the parameters can be readily associated with changes in results.
Students can use the 'navigator' button to go to the second part of the exercise, where they are presented with a strobe-image of a bouncing golf-ball and are asked to make various measurements of ball sizes and locations. They then calculate and input the strobe interval, initial ball height, and horizontal velocity. At the end of the exercise, the student's answers are analyzed and feedback is provided.
Move the sliders with your mouse to adjust parameters.
Move the ball by clicking and dragging it with the mouse.
Click "Start" at the bottom to 'release' the ball. The "Start" button becomes the "Stop" button, then the "Restart" button.
Click the 'Navigator' button to go to a different section. The exercise begins with 'Practice', the next sections is the 'Measurement' section, and there is a 'Help' section with more detailed instructions.
