Searching for Magical Physical Phenomena What are the magical physical phenomena in life?

I think that if you want to be original, the more interesting and murderous thing is the optical illusion phenomenon related to physical effects.

This is where some information comes out.

1. The quartz clock hanging on the wall wall often stops at the position of "9" on the dial when the battery is exhausted and stops moving. This is due to the fact that the second hand is most hindered by the gravitational moment at the "9" position.

2. Sometimes when the water pipe discharges water from the adjacent faucet, there is an occasional burst of noise. This is due to the resonance of the water pipes caused by the water flushing out of the faucet.

3. When taking pictures of the TV screen, the camera flash and indoor lighting should be turned off, so that the ** picture is clearer. Because the reflected light from the flash and lighting on the TV screen can interfere with the transmitted light of the TV picture

Physical phenomena refer to the change of the form, size, structure, and properties (such as height, velocity, temperature, and electromagnetic properties) of matter without the formation of new matter.

In other words, physical phenomena refer to physical events or physical processes that can be directly perceived, and are different from physical essences, which are abstractions of the common essential properties of similar physical phenomena.

First Explanation:

At high speeds, a slight adjustment of the radius can create a large centripetal force, which can be corrected by the greater the deviation of the center of gravity.

Even when it is very slow, the driver has to constantly adjust his posture to balance the center of gravity of the car so that the forces on both sides of the vehicle have less relative error.

When you are stationary, you cannot adjust this state, so it is easy to fall down.

Second explanation:

The reason why a motorcycle doesn't fall is basically the same as a coin: everything that rotates at high speed has the ability to keep the direction of the axis of rotation unchanged so that they don't fall to the sides. The same is true for the spinning top not to fall.

When we ride, we give the motorcycle a force in the direction of travel, so that the wheels turn, the wheels can maintain a certain state of balance, and then use the handlebar to adjust the balance, and the motorcycle can go forward. But as soon as it stopped, the car would lose its balance and fall over.

The third explanation:

When the top rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. In other words, the top rotates around its axis on one side and "revolutions" around its vertical axis on the other. The speed of the "rotation" of the spinning top around its own axis determines the size of the swing angle of the gyroscope.

The slower the rotation, the greater the swing angle, and the worse the stability; The faster it rotates, the smaller the swing angle and therefore the better the stability. People ride motorcycles for much the same reason. The difference is that one is a conical curved motion and the other is a linear motion.

When the gyroscope rotates at high speed, under the action of the gravitational couple, it does not fall over in the direction of the force couple, and the vertical axis of the fulcrum of the detour moves in a cone, which is the gyroscopic principle.

The equilibrium state at rest is easily disrupted. Balance while driving is dynamic balance, which destroys the control of the descendant to restore it so that it does not fall.

Fourth Explanation:

Matter has the property of maintaining a state of motion. The faster it moves, the more it can be maintained. Therefore, as soon as a moving object comes to a stop, its ability to hold on is rapidly decayed.

Fifth Explanation:

It's similar to walking on stilts. The principle is to use two points of movement to maintain balance. That is, through the control of the relative position of the two moving points and the center of gravity, the center of gravity can be kept above the two moving points, so as not to fall.

On motorcycles and bicycles, the relative position of the two moving points and the center of gravity is mainly adjusted by fine-tuning the direction of movement of the front wheels.

Hope!!!

When the motorcycle is moving, the car as a whole is moving forward, the wheel itself is also rotating, the rotating object is like a rotating top, will autonomously keep the direction of its axis of rotation unchanged, when it is normal not to fall, the axis of rotation of the wheel is parallel to the ground, if it is tilted, the axis of rotation of the wheel is oblique to the ground, and the axis of rotation when riding will automatically keep its axis parallel to the ground, so it will not fall.

When the motorcycle is tilted, the gravity can be broken down into two components, one of which is the centripetal force of the motorcycle turning, because there is a centripetal force of speed and centripetal force, so the motorcycle will just turn and will not fall.

However, when at rest, the body tilts, and the two forces that are decomposed by gravity do not provide centripetal force (because the person is stationary or slow), so it takes a lot of force to make the person not reach.

To see whether an object is moving or stationary, it depends on whether the force is balanced.

When a motorcycle is moving, it will move forward because it is subjected to a force in a certain direction (forward power).

When the motorcycle is stationary, if it is not framed, the center of gravity of the motorcycle will deviate, that is, the force is unbalanced, so it will fall to one side.

The faster the object moves, the more it tends to maintain the original state of the object, that is, to achieve stable equilibrium.

1. All of them will also be affected.

What you mean is whether the insulating oversized eraser can block the electric field. The answer is: no.

The electric field is a special substance that exists in the space around the electric charge and the changing magnetic field, which is invisible and intangible, but objectively exists. No substance can block the electric field.

The only way to make it feel like an electric field doesn't exist is to add an electric field that is the same in reverse (the combined field strength is zero, but the original electric field is not affected).

In fact, you can analogy gravity force fields (both belong to field forces), and nothing can block the gravitational field. Only the gravitational force can be balanced, and the resultant force is zero, which makes people feel the same effect as not being forced, but the gravitational field is still there.

Here's what you're adding.

First of all, it is necessary to know the relationship between neutrons and protons.

Protons get a negative charge and neutrons are formed.

When a neutron emits a negative charge, a proton is formed, and when there are neutrons in the nucleus, there is a repulsive force between the protons, but the two protons come together because they compete for one of the negative electrons in the neutron. That's why there is no dispersion.

This is different from macroscopic matter.

What is an insulator? There is no free moving charge inside the insulator, so it cannot form an electric current and cannot conduct electricity.

But the insulator does not have the ability to block the electric field. A field is a necessity, and the field at a certain point is a vector superposition of the fields produced by all the charges in space.

You can put something in it so that B has zero electric field force at point B, as long as the electric field generated by the thing you put in is the opposite of the electric field generated by A at point B. But the electric field generated by A at point B is always that much.

You put in an oversized eraser and no new charge is introduced to counteract the electric field generated by A. Even if it is thought that the eraser will produce polarization, this polarization charge only changes the dielectric constant in the region where the eraser is located, and eventually the electric field at point b will change somewhat, but it will never become zero.
