Since the beginning of the war, more than 2000 civilians have been killed by Russian missiles, according to official data. Help us protect Ukrainians from missiles - provide max military assisstance to Ukraine #Ukraine. #StandWithUkraine

AREOMETER Concentration and density data are in constant demand. The strength of alcoholic beverages, the quality of acid in a battery, the condition of antifreeze, saline solutions, and the content of soluble substances in juice are just a few of the tasks where areometers are indispensable.

The way soap acts? Liquid molecules experience mutual attraction forces, thus causing surface tension. By getting into the surface layer of water, soap molecules noticeably weaken the surface tension forces. Soap and laundry detergents reduce the surface tension of water, increasing its permeability. Therefore, soapy water soaks in and cleans fabrics and other materials, taking the dirt away with it.

If we place the lens on the window sill and get an image of distant objects outside the window on the screen, the distance between the lens and the screen will be equal to the focal length.

The drops of water act as a collecting lens, the image for the observer is inverted. A collecting lens is a lens which is thicker in the middle than at the edges.

If the Moon were a giant mirror.

In fact, it is an optical illusion. In this video, the frame rate of the camera unit coincides with the rotation frequency of the helicopter blades. That is why it appears that the blades are not rotating.

Rehbinder Effect visual demonstration It represents an adsorption reduction of strength — a change in the mechanical properties of solids due to physical and chemical processes causing a decrease in the surface energy of the body. In the case of a crystalline solid, what is also significant is that the crystal exhibits the defects in structure necessary for the nucleation of cracks, which then propagate under the influence of the medium.

Levitating pots with houseplants The levitation effect is realized with the help of magnets in the planter and the stand.

A clear process on the fuel consumption in a rocket.

Besides liquid in the flask, there is also gas, which expands when warmed by the heat of the hand. The temperature of the gas rises, so the pressure of the gas also grows. Increasing pressure of gas inside leads to the fact that the liquid begins to move upwards, against gravity, to the part of the flask where the pressure is less. When the gas in the lower part cools down, the liquid comes back down again.

The law of momentum conservation for rotational motion.

When the volume level gets above 155-160 dB, the car starts shaking and almost bursting with vibration. At low frequencies, the windows burst.

Steam machine When water is heated, intense vaporization occurs. The vapor pressure rises, eventually causing the cork to fly out.

Surface tension, taking soapy water as an example.

Oscillation in an elastic medium When striking the tuning fork, vibrations arise inside, they are almost invisible, only slightly audible. As soon as the horns of the tuning fork are submerged in water, a whole storm is born.

The oscillation of the candle, by melting the wax and reducing the mass. And then inertia enters the process.

The Mandela Effect When the first bead pops out of the box and rushes down, the angle between the first bead and the one following it changes and they collide.

The piston pump When the piston moves upward, the liquid under atmospheric pressure enters the tube, lifts the bottom valve and moves behind the piston. When the piston moves downward, the liquid under the piston presses on the bottom valve and it closes. At the same time, the pressure of the fluid opens the valve inside the piston, and this fluid moves into the space above the piston.

Sports are sports, but no one has ever cancelled the knowledge of physics.

Cleaning the tangerine by pressure

Polarization of light is a property of light, resulting in the vectors of electric and magnetic fields of light waves are oriented in a plane parallel to the plane in which light propagates. It occurs when light is refracted, reflected, or passes through an anisotropic medium.

Cleaning the tangerine by pressure

Sound pressure is the variable overpressure that occurs in an elastic medium when a sound wave passes through it.

Kittens enjoy physics too 😽

Wave Optics Light waves are regarded by their nature as electromagnetic waves, possessing all their properties.

In order to blow out plastic containers, you need a compressor. It is the compressor that generates the pressure by which the air jet is delivered.
