Why do eggs break when they fall, and how do eggs not break

This is mainly related to physics knowledge. To put it simply, because the hardness of the eggshell is much smaller than the hardness of the object he falls on, according to the knowledge of physics, we know that when they collide, the force between the two is the same, the force area is also the same, and the pressure generated is also the same, but the hardness of the eggshell is smaller, so it is easier to break under the same pressure. This is the reason why eggs are easy to break when they fall on the surface of a hard object.

On the other hand: why do eggs break? The compressive strength exceeds the upper limit of the material, according to the momentum theorem ft=mv

and the action reaction force, the force on the two objects is equal when they collide, and if the pressure caused by this force does not exceed the pressure of the other object, then the egg will break.

The forces that they experience when they collide are action and reaction. This means that they have the same impulse. And because the structural properties of the two objects are different, the final result is different.

Let's say. Eggs hit stones Both objects are subject to the impulse of x. While the egg can only withstand an impulse of x-100 or it will shatter, but a stone can withstand an impulse of x+10000, so it's fine.

This is the reason why eggs do not break when they hit stones (of course, if the speed of the eggs is too high, there is also a possibility that the eggs and stones will break together).

Because when the egg falls, the contact surface is stressed f = mv t (m is the mass of the egg, v is the instantaneous velocity at the beginning of contact, t is the action time between the egg and the contact surface) when f > the force that the egg shell can bear, the egg will be broken; Otherwise, it will not be shattered.

The reason why the egg will break when it falls is the problem of the contact area, the contact area of the egg is very small when it lands, and the pressure is very large; If the sponge is layered in the ground when it hits, it will not break, which is the result of buffering.

Because of gravity, the egg has a gravitational acceleration g during the fall, and the velocity reaches a great speed when it is close to the ground, colliding with the ground. Since the egg impulse is large enough, and the action time is small, the action force is very large, and the egg is broken.

It is well explained by the physical formula, m*v=f*t, when the egg falls to the ground, the momentum reaches the maximum, and when it collides with the ground, the instantaneous deceleration is 0, and the reaction force is very large, so it breaks.

According to the momentum theorem p=ft, the initial momentum is not 0, and at the moment of touching the ground, the momentum is reduced to zero. At the moment when it falls and touches the ground, the time of action is extremely short, that is, t1-t2=0, so the force f is very large, and the eggshell is "squeezed"!!

When the egg falls, the potential energy is converted into kinetic energy, and when it falls to the ground, the kinetic energy becomes zero, which requires strong work, and the work needs to be displaced, and the displacement can only be achieved by the position of the egg's center of gravity, so it will break.

Because the eggshell is too thin, the impact force can't withstand it!

According to the momentum theorem, ft=mv, the mass is constant, the velocity when falling will be, the time t is very short, so f is large, and the egg shell is not very strong, so it will break under the action of force.

The question is like, why did the apple hit Newton's head back then, and why did Newton have a headache to find the apple.

It should be that the egg cannot withstand the energy converted from kinetic energy to potential energy, so it will naturally deform, and due to the nature of the eggshell, it will break.

Because the outer shell of the egg allows less external force, and a violent impact will inevitably cause the egg to break.

Because the downward force of the egg during the fall is greater than the bearing force of the eggshell.

Principles of physics, related to momentum impulses. The velocity of the egg is greater when it falls, and the impulse is also greater due to the momentum p=mv. The moment the egg hits the ground, momentum can be converted into impulse according to the momentum theorem.

The impulse i=ft, the time is infinitesimal and can be approximated as zero, so the egg is subjected to a lot of force at the moment of landing, and the egg shell cannot withstand it and cracks.

When the egg is in contact with the ground, there is a greater velocity, and at the same time, the ground should generate an upward force to reduce the velocity of the egg, i.e., f=a*mAnd this force acts on the eggshell in one direction, making it easy for the egg to break!! +

Because the moment the egg falls on the ground, it collides with the ground and produces a mutual force, and the force generated by the egg is much smaller than the force on the ground facing it, so the egg will break...

The egg falls to the ground, and the reaction force on the ground is exerted, and the egg shell itself is very easy to break, and the egg itself is only partially stressed.

The imbalance of the forces that the egg is subjected to by the ground leads to an imbalance in the physical media connection.

Why do eggs smash when they fall dizzy!

Don't say that eggs will be smashed if they fall down! Even if you fall down, it will be smashed!

There is always an opposite to everything! [Origin of Species].

Because there is a lot of momentum when it falls, and because the velocity is instantaneously zero, the egg is subjected to a lot of reaction force.

It was therefore crushed.

It's a very simple and common question, but we haven't paid attention to it, let alone thought about it, which means that you are very good at thinking, which is good!

It's like jumping off a stairs and you're going to be sloppy. Hey...

1 Gravitational acceleration 2 The action of force is mutual and determines the final fate 、、、 the egg

Because the egg has a weight, it interacts with the ground when it falls.

The shell of the egg is very thin, and it shatters when you knock it, and you can't figure out why you grew up eating anything.

Because it was a fall. It's like a person who falls down hurts ......

Because the egg shell is very thin and not strong, it will break.

Because the hardness of the eggshell is not as great as the object that collides with it.

Hehe, he's a fragile material, so it's broken.

Because of the gravitational pull of the earth, the eggs are sucked towards the ground.

Yes, because of the gravitational pull of the Earth, the object will fall downward.

Analysis: The cause of the shattering is that the maximum deformation of the object itself is exceeded.

To make the egg not break, is to try not to let the egg exceed its own maximum deformation process, there are many methods, as said upstairs, but the ultimate goal is not to grow the maximum deformation of the egg itself ......

Preparation materials: raw eggs, scraps of paper, small cartons (larger than the volume of eggs).

Canvas (try not to be breathable, square shape, slightly larger) cord.

Paper tube (you can use your own paper roll, about the same thickness as a pencil).

Experimental principle: 1: buffer device.

Two: deceleration device.

Experimental process: 1: Buffer device: 1) Put the shredded paper scraps into the carton, about 1 3 of the volume of the carton

2) Put the eggs in, and then put in the confetti, the confetti should not be too little, to be a little tighter, that is, when the carton is sealed, shake the carton to feel that the egg is moving. At this point, the carton is packed;

3) Fix the paper tube on the edge of the carton with transparent glue, so that the paper tube is in contact with the ground before the carton lands to play a cushioning role.

2: Deceleration device: 1) Tie the cord to the four corners of the canvas.

2) The other end is fixed to one of the top corners of the carton (note that it is the same top corner).

The device is complete, and you can try it out!!
