Here’s the skeleton of the bounce program. Copy and paste into a new program.

from visual import *

floor = box (pos=vector(0,0,0), length=4, height=0.1, width=4, color=color.blue)
ball = sphere (pos=vector(0,10,0), radius=2, color=color.magenta)
ball.velocity = vector(0,0,0)
dt = 0.01

#the 1 after the while is interpreted as "true" when this program runs,
#basically turning this into an infinite loop.
#The loop is obviously incomplete, but think about what you would need to add
#to make this ball "bounce." It should accelerate at 9.81. You will need to
#include an if/else argument.
while 1:
 rate (100)
 ball.pos = ball.pos + ball.velocity*dt

Watch the following tutorial on adding while loops to your programs. Follow along on Glowscript making sure you type in the code exactly as he does. Punctuation, capitalization and spacing are annoying important in coding.

Try these practice problems on electric circuits:

• Series Circuit
• Parallel Circuit
• Parallel in Series Circuit
• Series in Parallel Circuit
• Parallel in Double Series Circuit (BONUS- annoyingly complicated)

This is going to be a great semester.

Happy Physics-ing!!
