I saw many friends who couldn’t solve the heavy stones in Chapter 21, and even ridiculed the physical common sense of the house pig. The house pig feels necessary to explain.

Galileo Leaning Tower Test Many people know that one big and one small two iron balls fall from the leaning tower at the same time, and they fall to the ground. Some people say that they are in the elementary school textbooks. However, the elementary school textbook does not say the knowledge of junior high school, that is, wind resistance and Air buoyancy.

The buoyancy of the air is small, but it also affects larger objects. In addition, the greatest influence on the acceleration speed of gravity is the air resistance and wind resistance.

When a person falls from a high altitude, the wind resistance will offset the acceleration and let the falling speed reach a fixed value. The setting is 25 meters to 50 meters per second, which cannot exceed this speed.

The density of the stone is seven times that of the human body, the potential energy is greater, and the wind resistance is less, so the speed can be faster.

So, is the Galilean leaning tower test correct? Who is the fastest one, one big and one small and two iron balls are falling at the same height?

We use junior high school physics to calculate.

Two round stones are big and small, the air resistance Fw=1/16·A·Cw·v^2 is set to CW=1, A1=1, A2=r^2, mass m1=1, m=r^3. r>1, air resistance FW1=1/16*V1^2FW2=1/16*V2^2*r^2

Gravity: G1=g, G2=r^3*g

1. If the same speed, the acceleration a1=(g-1/16*v^2), a2=(r^3*g-1/16*v^2*r^2)/r^3=( G-1/16*v^2*1/r)>a1a2>a1, the large stone has a fast acceleration.

2. When the limit speed is reached, the speed does not increase. Then 1/16*v1^2=g, 1/16*v2^2*r^2=r^3*g, 1/16*v2^2=r*g, V2>V1, uniform movement of large iron balls The end speed is large. So the big iron ball first landed.

3. It is more difficult to calculate in the case of calculating air buoyancy, but there is a simple way to test it in water. The water also has buoyancy. Take an iron ball and a piece of meat and drop it to see who will land first. Obviously the iron ball landed first.

You can also use a similar test, that is, an ant, and an ant on a stone at the same time falling from the air, the same height, which first landed?

There is still doubt about this, go to the middle school physics, calculate more, don't take it too much.
