Question 2 You can make the puck travel in complex
ways by placing a set of charges around on
the field. So, here’s your game challenge:
Arrange sources charge around to propel
the puck from its starting position into the
goal. That’s pretty easy for a straight shot;
you just put a negative charge behind the
goal. But what if there are barriers along
the way? This is a real test of your physical
understanding, including Newton’s laws of
motion and electrostatic forces. Game’s on!

Part A

On the control bar, check the Trace and
Field boxes. The game has three Difficulty
levels. Start with Difficulty level one and
arrange source charges to get the puck
into the goal. Once you’ve made a score at
any level, increase the Difficulty level. Take
a screen capture of two of your most
difficult goals and paste them here. At least
one of these should be at Difficulty level 2
or 3.
