### “My Egg Safety Device”

Name and Date

Appearance and Materials
• My device looks like ……..
• I used cardboard, a coffee can, some foam padding, and string to protect the egg
The Physics
• The egg will be traveling 20 feet (6.1 meters)
• Time to fall, from Distance = ½*g*t^2 is 1.12 seconds (with no air resistance).
• Max speed from acceleration, v = g*t is 11m/s
• Mass of egg = 60 grams or 0.060 kg
• Momentum = m*v = 0.66 kg*m/s
• Potential Energy of Drop = m*g*h = 3.6 Joules
•  Required Impulse = 0.66 kg*m/s
•  Required work on egg = 3.6 Joules
The Physics
• Newton’s First Law – Inertia: egg keeps going
• Newton’s Second Law – Forces cause accelerations
• Newton’s Third Law – Foam pushed egg, egg pushes foam
• Momentum and Impulse – Impulse causes changes in momentum, Impulse = F*t
• Work = Change in Energy – Work = F*distance
My Egg Safety Device Will….
• Reduce forces on the egg by …….
• (Work = Force x Distance)
• (Impulse = Force x time)

Describe the materials that reduce the force on your egg. Compare your design to car safety devices and sports equipment designed to protect your “egg”.

Some things I tried that didn’t work
• Dropping a live chicken
• Using a zip-lock bag full of marshmallows (might actually work!)
• Wrapping rubber bands around it to make it into a “super-egg”
