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.
How does Newton’s 1st law apply to 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.
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.
What physics principle is used to make a surviving egg drop project?
Inertia. Newton’s Laws of Motion are the basic principles illustrated in the egg drop experiment. Sir Isaac Newton published his Laws of Motion in 1687 and fundamentally altered scientists’ understanding of the world by describing the relationship between force and motion.
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.
What is the conclusion of the egg drop experiment?
Conclusions/Discussion The results of this experiment support the hypothesis. It is possible to make a container that can prevent a raw egg from cracking when dropped from about 15 feet above the ground. All of the cushioning materials worked successfully.
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 is the purpose of an egg drop project?
Purpose: To explore concepts of momentum and collision by developing a container to lessen the force of impact when an egg is dropped from a high place.
How does gravity affect the egg drop project?
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.
How is momentum used in an egg drop?
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 causes the egg to change state of motion?
When you spin the raw egg, its centre of gravity (or balance point) changes as the fluid inside the egg moves around. This results in a wobbling motion in order to achieve balance. When the hardboiled egg is spun, the solid centre has a fixed centre of gravity, causing it to move at the same time as the shell.
How do you drop an egg without breaking it physics?
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.
What are the best materials for an egg drop?
- Raw egg, or other payload that needs protecting.
- Container, like a cardboard tube, cup, box, etc.
- External protection materials, like balloons, rubber bands, craft sticks, straws, etc.
- Internal padding, like fabric, packing materials, paper, etc.
- Pen or pencil.
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.
What is Newton’s third law?
Newton’s third law simply states that for every action there is an equal and opposite reaction. So, if object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A.
What is the law of inertia in physics?
Newton’s First Law: Inertia Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to resist changes in a state of motion is inertia.
Which will cause the ground to experience a larger force during the fall the egg surviving or the egg breaking?
Answer 1: If the force of the egg striking the floor or ground is greater than the force that the egg shell can exert on itself to keep its shape, the egg will break. Some eggs are stronger than others, depending on how thick the shell is.
What 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.
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.
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.
Is energy conserved in an egg drop?
At the end of the drop, the egg and rubber band system now possess less gravitational potential energy, no kinetic energy (it is not moving) and a lot of elastic potential energy due to the stretched rubber bands. This illustrates the Law of Conservation of Energy.
Why does an egg not break when dropped on soft foam?
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. (The pillow also spreads the force over a larger part of the surface of the egg, which also helps save it).
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.
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.
