3rd Law. 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 physics behind the egg drop?
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?
What forces affect 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 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.
How is energy transferred in an egg drop?
An egg raised above the ground has potential energy due to the force of gravity. When dropped, the egg’s potential energy is converted into the kinetic energy of motion.
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 can you control the forces that cause an egg to break?
How can you control the forces that cause the egg to break? Gravity cannot be controlled, but it can be contradicted by air friction. To control air friction, surface area can be increased, as done by the fabric surrounding the box. Wind can be dealt with by avoiding it, or making the model stable.
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.
Does the egg possess inertia?
The raw egg keeps spinning after you touch it briefly because the liquid egg inside remains in motion, it’s inertia is greater than that of the solid interior of the hardboiled egg. An object’s momentum is its resistance to changing its state of motion; roughly “how hard it is to stop”.
How does momentum affect an egg drop?
When you drop the egg, it speeds up as it falls, and as it speeds up, it is gaining momentum from the impulse caused by the force of gravity. When it hits the floor or the pillow, it stops due to an impulse in the opposite direction.
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.
- Paper.
- Tape.
- Scissors.
Why do straws work in egg drop?
As the whole structure rotates, a different long straw hits the ground and the process repeats.
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.
Can an egg break on grass?
If an egg is dropped on concrete, it usually breaks. If an egg is dropped on grass, it may not break.
What is the best shock absorber for dropping an egg?
Foam from an old cushion, cotton balls, cotton batting, stuffing, bubble wrap, old rags, toilet paper or paper towels can be used for the first, dense cushioning layer closest to the egg.
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 do you drop an egg without breaking it science 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 does an egg break when dropped on the road but not on the grass?
A moderate force will break an egg. However, an egg dropped on the road usually breaks, while one dropped on the grass usually does not break because for the egg dropped on the grass, a) the change in momentum is less.
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 does the concepts of impulse and momentum apply to an egg drop experiment?
In any collision, the momentum change is equal to the impulse. So if the egg dropped from 5 meters has the greater momentum change, it will also have the greater impulse.
How much force can an egg withstand when dropped?
Putting all of it together into the equation F=m*(dv/t), the force to break the egg is 24.5 N, or around 5.5 lbs. Answer 4: When you drop the egg, it accelerates due to gravity. This means that the force of gravity pulling on the egg will cause the egg to go faster.
How much energy is required to break eggs?
Eggs would produce the cracks when suffering from an impact energy of 12-26 mJ.
How much pressure does it take to break an egg?
Usually, it takes a little more than 5 ½ pounds of force to crack an eggshell — much less than the weight of a human being — but the precise amount of force needed depends on the direction in which that force is applied and how much the force is distributed (or not) over the surface of the shell.
What’s Newton’s 4th law?
Any object has a tendency to stay in its current state. This tendency is called inertia. Any object has a tendency to stay in its current state.
