The balance is achieved according to the principle of the lever, on the lever each end has a small plate, on one end you put the weight, on the other end you put the object to be weighed, the lever is equipped with a pointer, when both ends balance, both ends of the mass (weight) are equal.

A cable-stayed bridge is a type of bridge in which the main girder is pulled directly to the bridge tower by several cables. It is a structural system combined with the pressure tower, the tension cables and the bending beam body. The two piers of the cable-stayed bridge support the weight of the entire body of the bridge, and the weight of the entire...

Using compressed air to propel the car forward, an aerodynamic car uses a reservoir to store high-pressure air that then propels the car forward. So when you need high speeds, you need extra heat to make the high pressure air absorb enough heat to expand sufficiently giving it more power.

In order to mimic the reality of nature, the sun at the center of the solar system uses a lamp to illuminate the Earth and the Moon. The earth tilts in its orbit around the sun and the moon's orbit around the earth. In this way, the eclipses of the sun and the moon, the waxing and waning of the moon, the rotation and rotation of the earth, the change of...

Elastic potential energy is related to the elastic deformation of the object, while kinetic energy is related to the mass and velocity of the object. A tightly wound rubber band has strong elastic potential energy. When the airplane moves forward, the elastic potential energy of the rubber band decreases while the kinetic energy of the airplane increases....

In order to imitate the reality of nature, the sun at the center of the solar system is illuminated by a lamp to illuminate the Earth and the Moon. The earth tilts in its orbit around the sun, and the moon's orbit around the earth and the earth's orbit around the sun intersect at an angle. In this way, the eclipses of the sun and the moon, the waxing and...

In fact, the laser is not a mystery, its simplest principle is the reception of light from a mirror on both sides of the resonance cavity, with the reflection beam back and forth, the light in the resonance cavity is amplified, the wavelength has become uniform, and finally out of a small hole, is our everyday laser.

When activated the blades rotate rapidly to create wind force around the windmill. The force of the wind will propel the car forward. The stronger the wind, the faster the car goes, the softer the slower the car. The reaction of the air makes the car move magically. This is the law of action and reaction.

Learn about conservation of energy in physics. The chemical energy in the dry cell is converted into electrical energy, which is output to the motor via a cable. The motor converts electrical energy into mechanical energy so that the motor rotates. The motor is driven by the belt. The rotor in the generator rotates and cuts the magnetic field lines to...

The projector is based on the principle of convex lens imaging. When the object distance is between twice the focal length , the inverted magnified real image is formed. Place the inverted negative between twice the focal length of the convex lens, then shine the light on the negative, and the inverted real image will be projected on the screen.

The motor rotates at a high speed, driving the fan to exhaust air from the bottle mouth to the outside of the bottle, so that negative pressure is formed in the bottle, and finally suction is produced at the bottle mouth, and the paper debris is sucked into the bottle . The bottle cap can be closed at normal times, but can be rotated downwards during use.

The main use of salt water conductive principle. The zinc is more active than cooper,so the zinc is easy to lose electron and come to the positive pole. The cooper come to the negative pole.The salt water is act as the role of electrolyte. The electrolyte is a material that can conduct electricity. The salt water will be activated when mixed acetic acid....
