Is the buoyancy equal to the force on the object?

The magnitude of buoyancy is equal to the gravity of the liquid displaced by the object
F = liquid density * volume of liquid discharged * g
"G" is the relationship between the mass of the object and the gravity, which is 9.8n/kg,
In other words, the gravity per kilogram of object is 9.8N

What is the buoyancy of an object

The relevant calculation of buoyancy is as follows: I hope it answers your question and is helpful to your study:
1、 Weighing method: F = g in air - G in liquid
Weigh the gravity of the object in the air with a spring scale. Record it as G air. Then immerse the object in the liquid. The reading becomes smaller. Record it as G liquid. The reduced part is the buoyancy of the object
2、 Archimedes principle experimental result method: F float = g drain
According to the experimental results of Archimedes principle, the buoyancy of the object is equal to the weight of the liquid discharged by the object (g discharge)
3、 Formula method: F floating = P liquid V discharge G
If in the Archimedes experiment, instead of weighing the liquid weight, the volume of the liquid displaced by the object is measured. According to g = mg = P liquid V displacement g, the gravity of the displaced liquid can be obtained. That is, it is equal to buoyancy
4、 Pressure difference method: F floating = f up - f down
The object is immersed in liquid. The pressure of front, back, right and left can offset each other. The upward pressure on the bottom is greater than the downward pressure on the surface. The object is generally subjected to a vertical upward supporting force, which is buoyancy. Therefore, buoyancy can be calculated according to the pressure difference
5、 Equilibrium condition method of floating body: F = g self = P object v object G
Floating bodies include floating and suspended objects. Because they are still, they receive upward buoyancy and downward gravity, which are a pair of equilibrium forces. Therefore, they are equal in size. As long as the weight of the object itself is obtained, it is the buoyancy of the object
6、 Displacement method: F = displacement (kg) × g
The full load weight of a ship is generally expressed in terms of displacement, that is, the mass of boiled water discharged. The ship is also a floating body. According to the floating body balance condition, it can also be obtained that the total f floating received by the ship = g total. And the displacement (kg) × g. It is the weight of the ship's boiled water, that is, the buoyancy and the total gravity of the ship and cargo

At an altitude of 1125m, an aircraft flies horizontally at a speed of 86.6% m / s 14. At an altitude of 1125m, an aircraft flies horizontally at a speed of 86.6m/s (G is taken as 10m / S2) Requirements: (1) how long does it take for an object falling from an aircraft to land? (2) How far does the object move horizontally from falling to landing? (3) The speed of an object at the end of 5S from falling

(1)h=1/2gt^2 t=15s
(2)S=vt=86.6*15=1299m
(3) Vertical direction V1 = GT = 50M / S
Then add the square of V1 and the square of V to open the root sign

How to test the altitude between the aircraft and the ground when flying in the air?

There are two kinds of altitude measurement. The total static pressure system in the atmospheric data system is used to measure the altitude. The principle is no different from the ordinary altimeter. The altitude is inversely proportional to the air pressure, but this system measures the altitude of the aircraft relative to the international standard sea level. The other system is the radio altimeter, It is used to measure the actual altitude between the aircraft and the ground. The principle is that the electromagnetic wave is sent from the aircraft to the ground and will be accepted by the receiver on the aircraft after being reflected on the ground. Theoretically, the time between transmitting and receiving the reflected wave can be measured, plus the propagation speed of the electromagnetic wave to calculate the altitude. However, the radio altimeter is generally used at low altitude, which is too short, Measurement is basically impossible, so time will not be measured directly. Instead, time is calculated by measuring the frequency difference between reflected wave and transmitted wave

How high do planes usually fly?

Civil aviation aircraft above medium-sized are flying at high altitude. The high altitude here refers to the space with an altitude of 7000-12000 meters. In this space, 1km is used as an altitude level, which is divided into six altitudes: 7000, 8km, 9km, 10000 meters, 11000 kilometers and 12000 kilometers. Aircraft flying at high altitude are only allowed to fly above the given altitude. In addition
