The Egg Drop
by Bianca Jackson, Krystal Jean-Batiste, Sharhonda Biley, Alexis Hayes According to equilibrium rule number two, an object that does not change direction or speed up or slow down has no net force on it. The gravity will pull down on the egg while the egg will pull upward. The egg will remain in motion until it hits the bottom of the bucket according to Newton's first law. The egg does not have a lot of mass so therefore the inertia is also small. So, it has less tendency to resist changes in motion. The net force is pulling down, causing the egg to fall downward and accelerate downward in that direction according to Newton's second law. For every action, there is an equal and opposite reaction. While the egg is pulling the parachute down, the air will push it upward. If the egg is safely cushioned, it will not crack. When the straws hit the bottom, it will make a little bounce, thanks to Newton's third law! |

Students in my physics classes put Isaac Newton's 3 laws of motion into action by designing parachutes to cushion the fall of a raw egg. Using 20 straws, three balloons and 1 meter of tape, the students had 20 minutes to fashion their parachute. Working under tight time and material restrictions, we had a 50% success rate! Congratulations to the physics students at North Central High School! | |||||||
