Anonymous users2024-02-11In fact, it will change, because although the inertia of the earth makes the helicopter the same speed as the earth, but our air is the resistance of the resistance to the inertia of the aircraft is less and less, and it is slower and slower, so there is a deviation when it falls, but you basically can't see that little bit of deviation, because your inertia is small and flies very slowly and the speed of the earth's rotation, the resistance of the air is extremely small, if you mark on the ground, you can see the deviation if you fly for more than half a day. Then you fly for 1 or two hours, of course, the deviation will not be seen, and when you jump up on the spot, there is the same air resistance as a helicopter, because you fall too fast, so the slight deviation is completely invisible.

Anonymous users2024-02-10No, because the earth has a gravitational attraction, no matter where the plane is located, there will be a gravitational pull between the plane and the plane, and the gravitational force will attract the plane, so the position of the plane will not change (unless the plane flies out of the earth).

Anonymous users2024-02-09No, because the plane has inertia, and the inertia and the earth move at the same speed, even if the earth is the reference, the plane is stationary, so it will not change. It's like Sputnik.
It is said that motion is absolute, and rest is relative.

Anonymous users2024-02-08Won't change. Because the helicopter moves with the earth before leaving the ground, after ascending, the helicopter is also moving due to inertia, so it stays in place after falling.

Anonymous users2024-02-06Theoretically, it should, but the loudspeaker also relies on air to stop in the air, and the air is constantly moving, so it is difficult to say that the loudspeaker will not stop in a circle.

Anonymous users2024-02-05People stand on the earth and jump upward, and when they fall, they fall to the same place, and this is due to inertia.
This is not due to inertia. This is due to the fact that the person is always subjected to the force of gravity (g=mg).

Anonymous users2024-02-03Hello, if the speed of the vehicle is the buried ruler v meters, and the distance from the factory to the chief engineer's residence is s meters, then the time required for the chief engineer to travel from home to the factory.
t=s v and set the day when the car departed from the factory and walked 1 meter away from the factory to meet the chief engineer, and the chief engineer walked for t2 minutes, then the car traveled 1 meter time.
t1=s1／v
There is it according to the title.
t1+t2=s1 v+t2=(t-10)+60 The car travels 2 less (s-s1) and returns to the factory 10 minutes early, so there is.
2(s-s1)/v=10（
It means that the cover grip saves half of the travel distance of 10 minutes for the car, because it is a round trip) The chief engineer walked for 55 minutes on the road.
Method two. Set engineer speed v1 and vehicle speed v2
Normal traffic t0
The engineer walked and met the trolley.
v1t+v2(t0+1-t-1 6)=v2t0, i.e., v1t=v2(t-5 6).
v1t=v2*(1/6)*(1/2)
It means that half of the travel distance saved by saving 10 minutes for the car, because it is a round trip) Lianli: t = 11 12
Namely: 55 minutes.

For example, trying to measure the depth of seawater with a wire is often not possible, because as the depth of the sea increases, the wire lengthens, and when the maximum tension of the wire is exceeded, the wire is broken. You may think, the maximum tensile force of thin steel wire is small, why not use thick steel wire? If you think about it, no, the wire is thicker and the gravity increases, so it is impossible to measure the seafloor at a depth of about a kilometer.
The above analysis is qualitative, and if it is analyzed quantitatively, this problem is still a bit difficult.

Anonymous users2024-02-01No, the object hanging on the rope breaks because the rope is stressed more than it can withstand at this node. And the gravity of the whole rope does not act on one point, so it will not break.
1. It's better for you to ask this question, roughly: air resistance, the friction of the wire rope, are all there, so this is generally good. You're right. >>>More
It's a single pendulum, swinging from the lowest point to 30 degrees, swinging back, but in the opposite direction. Note that at this time, the second bullet has not yet hit the sandbag (critical), and the second formula in the analysis is a negative sign before v, and the positive direction is v1 and v2. From the conservation of mechanical energy, kinetic energy is converted into potential energy, and the position is the same, so the initial velocity is the same.
1.Choose C, after many reflections of the mountain clouds on the ground, the actual propagation distance is large and small, so that we can hear thunder many times, in fact, a lightning itself only produces one thunder. For example, if two mirrors are placed opposite each other or at an angle, we can see many images in the mirror. >>>More
No contradiction You misunderstood that molecules that attract each other do not fit close together when the distance between molecules d=r gravitational force = repulsive force; In other words, "the experiment of the lead blocks close together shows that there is a gravitational force between the molecules", and the distance between the molecules must be at least greater than r, how can they be close together?
Physics is the science most closely related to human production and life. It has become the bounden duty of physics teachers to connect physics knowledge with production practice and life practice in physics teaching, so that students can understand the application of physics knowledge in production and life practice as much as possible. >>>More
