answer
When dropped from 10 meters
question
When a large egg is dropped from a height of 10 meters, upon which landing surface did the egg break entirely?
answer
When landing on the hard floor, When landing on the 1-inch piece of foam
question
How do the three surfaces compare in terms of providing the egg with a safe landing? Which ordering below ranks the three surfaces from least safe to most safe?
answer
hard floor < 1-inch foam < foam box
question
Which statement describes the effect of increasing drop height upon the force encountered by the egg when colliding with the surface?
answer
he force is directly related to the drop height
question
Trials with which two sets of experimental conditions would allow an experimenter to determine the effect of increasing drop height upon the force experienced by the egg? Select two.
answer
size: large, drop height: 1 meter, surface: hard floor
size: large, drop height: 10 meters, surface: hard floor
question
Small egg dropped from 5 m onto 1-inch foam. Jumbo egg dropped from 5 m onto 1-inch foam.
What could be the purpose of these two trials?
answer
To determine the effect of mass of an egg upon the force it experiences.
question

answer
Change the egg size to a large egg.
Change the drop height to 1 meter.
Change the landing surface to a box of foam.
question
Which of the following variations would increase the force experienced by the egg upon landing? Select all that apply.
answer
Increasse the drop height.
Increase the mass of the egg.
question
When a large egg was dropped from 5 meters onto a 1-inch foam surface, it landed safely. Which changes in conditions would lead to a fractured or a broken egg? Select all that would
answer
Change the egg size to jumbo.
Change the surface to a hard floor.
Change the drop height to 10 meters.
question
Which set of experimental conditions would result in the least amount of force on the egg?
answer
Drop a small egg from a height of 1 meter into a box of foam.
question
Which set of experimental conditions would result in the most amount of force on the egg?
answer
Drop a jumbo egg from a height of 10 meter on a hard floor.
question
What affect does doubling the mass of an egg have upon the force that the egg experience?
answer
Doubling the mass makes the force twice as large.
question
