Ball on a Ramp

Provided below is some code that is supposed to model the behavior of a ball rolling down an inclined plane. Run the code.

Find the variables below and record their abbreviations. Change them, one at a time, to see how they impact the code performance. Discuss what changes and what remains consistent:

• Ramp length
• Ball speed
• Time interval
• Number of books in the stack
• Acceleration

Reset variables to the following:

• Ramp length = 100
• Time interval = 10
• Number of books in the stack = 1
