Egg Drop Extravaganza
By Jessica M.
The goal of this project was to create an egg case that will increase the time of impact and decrease the force of impact on the object so the egg wont break
Describe your egg case:
The egg case had to weigh 1kg. My egg case consisted mainly of a somewhat small cardboard box . Attatched to the box were two small books duct taped to the sides. Inside the box my egg was wrapped in two small towels, and surrounding the towels there were layers of cotton balls, tissues, and paper towels. (I also added a few rocks to make the weight of the box more)
Did your egg break? No
Explain why or why not:
By putting the egg in a "case" there is more momentum, so the case w/ the egg inside is harder to stop (then the egg alone) so the more force or longer amount of time to stop it. The egg falling alone would be lighter (keeping in mind air resistance) decreasing time of impact (compaired to if it were heavier) which will increase the force of impact and increase the force of impact and increase acceleration.
"fig 7.5 if increase time of impact...decrease force of impact, if decrease time of impact...increase force of impact"
So by adding mass to the egg (the case) it will increase time and decrease force. After dropping the case my egg remained conserved, and force from the ground stopped the box from continuosly moving
Formulas you can use to calculate some of the things we experienced in the experiment:
(the delta signs dont show up)
v = gt
p = mv
p = J = Ft
Reflect on your design as a scientist or engineer would. How could you improve your design? Or what new design would you use in the future?
To improve upon my first case, i would figure out a better way to add mass inside of my box instead of having to tape books to the sides.
