  1. The Great Egg Drop

  2. Real-Life “Egg Drops” • Mars Rovers (2004) • Descent onto Martian surface • Giant airbags • Bounced on surface until coming to rest • Felix Baumgartner (2012) • Highest free-fall in history • Free fall altitude: 39045 m (128100 ft) • Speed attained: 1342.8 km/h • Free fall time: 4:20 min

  3. Acceleration: A Review • The rate at which the velocity of an object changes • Constant • Velocity (speed and/or direction) changes by the same amount every second • Changing • Velocity (speed ad/or direction) changes by a different amount every second Gravity Centripetal Forward

  4. Forces: A Review • A push or a pull on an object • Applied • Normal • Friction Applied FG Friction

  5. Newton’s First Law of Motion “Objects in motion stay in motion and objects at rest stay at rest unless acted on by an external force” • All objects have inertia • A tendency not to change their motion • Remain at rest • Remain in motion

  6. Newton’s Second Law of Motion “The acceleration of an object is created by a net force on the object” • F = m a • For a given object, a larger force generates a larger acceleration • For a given force, a higher mass generates a lower acceleration

  7. Newton’s Third Law of Motion “For every action, there is an equal and opposite reaction”

  8. Egg Drop Requirements Overview • Materials • 4 types can be selected • Limited supply, so plan ahead • Size • Must fit inside a 10” sphere • Design • Complete accurate sketch before beginning construction • Must be approved before building • BE CREATIVE!!! • Remember, a simple shell doesn’t help the egg survive alone!
