Does Newtons of an Egg drop vary accordingly to height?

In summary, when an egg is dropped from a high height, its speed increases as it falls, but the force it experiences is the same regardless of the drop's size.

According to my knowledge, I am able to apply Newton's second law on an egg for an egg drop; the resulted force from that can would be the force which occurs when it hits the ground. That force would also be reflected when it hits the ground according to Newton's third law.

What is confusing me is that the same force occurs to a 2m drop and a 2cm drop; one breaks and one doesn't yet the forces are still the same?

I do not understand.

When the egg is falling to the Earth there is constant force acting on the egg and the Earth F=mg=const. But as they close together they pick the same momentum each P=mv in different directions so the whole momentum of the system stays 0. So the speed of the egg is increasing. The movement of the Earth is negligible.
If you drop the egg form hight of 2 m it will have higher velocity than from 20 cm so bigger momentum and bigger kinetic energy.
When the egg hits the Earth the force with which the egg will act on the Earth will depend on the change of the momentum or in other words on how fast the speed will decrease over time ( F=dP/dt=m dv/dt ).
If the egg fall on something soft the time of change of the momentum will be bigger so the force will be smaller and maybe the egg won't break even from hight of 2 m.

Can you explain more clearly what you are trying to ask about the Newtons of an Egg drop varying with height? Are you asking if the force of impact on the egg changes depending on the height from which it is dropped? If so, then yes, the force of impact will vary with the height of the drop. This is because the force of gravity, which is responsible for the egg's acceleration towards the ground, increases with distance. So, the longer the distance the egg falls, the greater the force of impact will be. Additionally, factors such as air resistance and the surface on which the egg lands can also affect the force of impact and contribute to the varying results between a 2m and 2cm drop.
 

1. What is the relationship between the height of an egg drop and the force of gravity?

The force of gravity is directly proportional to the mass of the object and inversely proportional to the square of the distance between the objects. Therefore, the higher the height of the egg drop, the greater the force of gravity acting on the egg.

2. How does air resistance affect the Newtons of an egg drop at different heights?

Air resistance is a force that opposes the motion of an object through air. As the height of the egg drop increases, the air resistance also increases, which can reduce the overall force acting on the egg.

3. Is there a specific height at which an egg will experience the maximum amount of force when dropped?

No, the maximum force an egg experiences when dropped depends on various factors such as the mass of the egg, the atmospheric conditions, and the surface on which it falls. Therefore, there is no specific height at which an egg will experience the maximum force.

4. Can the shape or size of an egg affect the Newtons of an egg drop at different heights?

Yes, the shape and size of an egg can affect the force it experiences when dropped from different heights. A larger or more aerodynamic egg may experience less air resistance and therefore a greater force when dropped from the same height compared to a smaller or less aerodynamic egg.

5. How can the Newtons of an egg drop be calculated at different heights?

The force of gravity acting on an object can be calculated using the formula F = mg, where m is the mass of the object and g is the acceleration due to gravity (9.8 m/s^2 on Earth). To calculate the force of the egg drop at different heights, the mass of the egg and the height from which it is dropped must be known.
