1. Explain the energy transformations that take place during an egg- drop investigation from the time the container has started being raised to the top of the door frame to the time it finally lands on the floor. 2. Describe the construction of your egg-drop container, explaining the reasoning for your design. If your container succeeded in preventing the egg from breaking, explain why you think it did. If it was not successful, describe a change you would make to improve it. 3. Apply the law of conservation of energy to determine the impact velocity of your egg-drop container (assuming no air resistance and using a door frame height of 2.0 m). 4. As mentioned in the lesson, an egg-drop container is like a helmet for an egg. Do research to find out how the helmets that protect the head are tested. Is there a resemblance to the test you carried out? Search through Lessons One through Four to find the word, phrase or law* which best fits each definition, description or statement. When you have finished, the list will be in alphabetical order. the rate of change of velocity with respect to time, a vector quantity. the force of friction acting on an object moving through the air (aka drag). the kind of relationship where an increase in the magnitude of one variable corresponds to an increase in the magnitude of the other variable. the change in position, a vector quantity. a push or a pull tending to change the motion of an object. an abstract diagram in which an object's environment is replaced by the forces it exerts on the object. a force which always opposes motion. a two dimensional representation of the relationship between variables. the force of attraction between the earth and an object. the kind of relationship where an increase in the magnitude of one variable corresponds to a decrease in the magnitude of the other variable. * "Zero net force means zero acceleration." * "Acceleration varies directly with net force and inversely with mass." * "For every action force there is an equal and opposite reaction force." the perpendicular force exerted by a stable surface on an object in contact with the surface. the rate of change of displacement with respect to time, a vector quantity. Design an egg-drop device that will protect an egg during a 2.0 m fall. To do this, you must apply your knowledge of energy transformations and predict what materials could be used to protect your egg. A typical door frame has a height of 2.0 m. With this in mind, find a safe area to perform your egg drop. This should be an area where there is no risk of the egg device hitting someone on the way down and an area where there is no risk of damage due to the impact of the fall. (For example, if your device is pointy or heavy, it may leave a nice little dent or scratch in the floor! A cushion at the drop point might be a good idea.) Drop the egg in its protective "helmet." Hold the egg in position at the height of a doorway and release. Check to observe if your egg survives the fall intact.
