Game instructions

The object of the game is to navigate the monkey from one cliff to another by controlling his initial angle, intial velocity, and the gravitational acceleration as he swings on a vine. You can change these quantities in the control bars along the bottom of the applet. When you are ready to swing the monkey, push "GO!" and he will begin his journey.

Things to notice while playing the game

• How does the initial angle change where the monkey ends after he swings?
• What affect does a greater/lesser gravitational acceleration have on the monkey's journey on the vine?
• Does an increased intial velocity make the monkey travel more or less distance? How is this affected by his kinetic energy?
