Momentum change is the mass multiplied by the velocity change. You have just determined that the egg dropped from 5 meters has the greater velocity change. And since the two eggs have the same mass, it is the egg dropped from 5 meters that will have the greater momentum change.

What is the physics behind the egg drop experiment?
The cup drop illustrates the transfer of potential energy to kinetic energy. The potential energy from the eggs transfers into kinetic energy after an outside force (gravity) acts upon the egg.
What physics principle is used to make a surviving egg drop project?
The science behind solving the falling egg “problem” is found in Sir Isaac Newton’s laws of motion. The first law states that an object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an external unbalanced force.
What forces are acting on an egg drop?
A falling object (egg) has a downward force acting on it due to gravity. Air resistance acting on the falling egg results in an upward force, and these 2 forces oppose each other.
How does Newton’s law affect egg drop?
Newton’s First Law, once the egg was moving, it didn’t want to stop. The container of water interrupted the egg’s fall, providing a safe place for the egg to stop moving so you could recover it unbroken. The gravity-pushed egg caused the water to splash out.
How does Newton’s 1st law apply to egg drop?
How does Newton’s 3rd law apply to egg drop?
Newton’s third law states that for every action there is a opposite and equal reaction. Our egg drop project demonstrates this by there being a simultaneous reaction but in the opposite direction, so when you drop the egg and it lands, an upward force will act on it.
How do you drop an egg without breaking it physics?
What type of collision is an egg drop?
Elastic Collision BUT: Air resistance becomes negligible when the object falls at a constant speed and is no longer accelerating, also called terminal velocity.
What makes an egg drop successful?
Ensure that you have enough padding in the box to cover the egg evenly on all sides. When the box hits the ground, the force will cause the box to crush, which absorbs much of the shock of the fall. The force is also evenly distributed throughout and absorbed by the cushioning material.
How does acceleration relate to an egg drop?
When dropped, the egg is accelerated by gravity. When the air resistance (the force experienced when placing one’s hand out in a strong wind), which increases with increasing velocity, equals gravity, the egg’s velocity will remain constant. This velocity is known as terminal velocity.
Is momentum conserved in an egg drop?
The Vehicle increases the amount of time that the force of gravity is acting on the egg. The impulse equals the change in momentum so the only way to reduce it, is to reduce the initial momentum = mv because in the end it will be stop by floor and have zero momentum there. Conservation of momentum equals mv=mv.
Why does an egg break if dropped on a hard surface but doesn’t break if it lands on a soft pillow?
The egg dropped on the floor stops very quickly, which means the force on the egg is large, so it breaks. The egg dropped on the pillow slows down and stops more slowly since the pillow is squishy, therefore the force on the egg is smaller and the egg does not break.
Why does an egg not break when dropped on grass momentum?
When the egg hits the ground the forces of the impact are distributed around the shell so it does not break.
Why do eggs break when dropped?
Gravity causes an object to fall to Earth when dropped. Drop an egg from eye level so that it breaks. When the egg hits the ground with a given force, the ground exerts the same force back on the egg. The faster the egg falls, the greater this force is.
Where is the strongest part of an egg?
The egg is strongest at the top and the bottom (or at the highest point of the arch), which is why it does not break when pressure is added to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point.
What are the best materials for an egg drop?
- Raw egg.
- Newspaper.
- Masking tape.
- Balloons.
- Straws.
- Cardboard.
- Cotton.
- Toilet paper.
How can an egg survive a 100 foot drop?
- Slow down the descent speed.
- Cushion the egg so that something other than the egg itself absorbs the impact of landing.
- Orient the egg so that it lands on the strongest part of the shell.
Why does the egg fall right into the glass while the paper roll and the Pan fly sideways?
It’s all about Inertia! Inertia says an object, the egg in this case, will stay at rest, unless an outside force acts upon it, your hand in this case. When you move the pie pan with your hand, gravity takes over and pulls the egg straight down into the glass of water.
Why eggs dropped on a carpet or a mattress do not break?
Because a carpet or a mattress is soft in comparison to the floor, the egg slows down and stops more slowly, resulting in less force on the egg, which prevents the egg from breaking.
How do eggs not break project?
To drop an egg without breaking it, wrap the egg in wet paper towels and place it in a plastic bag of puff rice cereal. Fill 4 small bags with puffed cereal too, then put all the bags into 1 large container. You can also wrap the egg in packing material, like bubble wrap, packing peanuts, or inflated plastic packets.
Why are straws good for egg drop?
The key idea of a successful straw structure for egg drop project, from physics point of view, is to find a design that the straw will divert or absorb most of the forces, thus little force goes to the egg.
How much force does it take to break an egg vertically?
The average load to break the eggs when standing up was 53 Lbs. On their side, an average of 90 Lbs was required. This makes sense because eggs are flatter on their side, which allows more of the platen/foam to contact the shell, helping distribute the force across a larger area.
How Does height affect momentum?
Yes, momentum increases with height. As the object falls from a greater height there is an increase in the velocity. The formula for momentum is given by the product of mass and velocity. Since the velocity of the object is high at the time of impact the momentum will be high.
Which egg experienced the greater impulse?
Which egg experienced the greater time of impact? If their momenta are equal before the collisions (same mass and velocity), both eggs experience identical impulses because both are stopped by the collision. The egg that hit the crash barrier experienced the greater impact force due to the shorter impact time.
