Are there any effects on flying airplanes during earthquakes?
If the whole earth vibrates, objects attracted by it seem to feel the vibrations to some extent. Even though the plane is in the sky, there is an attraction with the earth. Like I take a magnet and put some iron pieces in the magnetic field. Then if the magnet moves, the iron pieces will also move.

Let’s compare it with generating 1,000MW of electricity.
See lessA 1,000 MW from Coal power plant
– Uses 2-3 million tons of coal
– Strip mining causes
– Environmental damage, acid leaching
– Deep mining causes deaths and harm to health
– Emits 7 million tons of CO₂
– Emits 300,000 tons SO₂, particulates, other pollution
– Releases 100 times more radioactivity than a nuclear plant
– Produces 600,000 tons of ash
– Accidents could kill people or lead to fires
A 1,000 MW from Nuclear plant
– Uses 30 tons of uranium
– Coming from 75,000 tons of ore
– Energy from the fission of 1 lbs of uranium equals 50 tons of coal
– Does not emit CO₂ when operating
– Produces no acid-forming pollutants or particulates
– Low levels of waste gas 250 tons of radioactive wastes require storage and disposal
– Accidents can range from minor to catastrophic
From this perspective, Nuclear power plant is better. But according to radioactivity, it is more harmful.

The sum of the mass of the Proton and Neutron exceeds the mass of the nucleus of an atom. This difference is called the mass defect. If we convert this mass defect into energy, this energy is called binding energy. This energy spends on nuclear binding.

In case of collision, if the total kinetic energy before the collision and the total kinetic energy after the collision between the objects participating in the collision are not equal or less, then the collision is called an inelastic collision. For example, if we say, two cars moving with a kinetic energy of 100 joules and 150 joules collide. Now after the collision, their kinetic energies are 80 joules and 120 joules. Here the total kinetic energy before the collision is 250 joules but after the collision, the energy is 200 joules. That is, 50 joules of energy have been wasted. Since there is no conservation of kinetic energy between them, we call this collision an inelastic collision.
All the collisions in our real life are inelastic. Because when any collision occurs, there is sound, heat, etc. generated. And these are the powers. And this power is generated from the kinetic energy of the two cars. Here some of the car’s kinetic energy is consumed. So the kinetic energy after the collision is less than the previous kinetic energy.

Why is friction called a necessary nuisance?
Have we ever thought, about what would happen if there was no friction? Once someone pushed from the back of the bike, the bike would not stop. It would go on. No more fuel was consumed.

Have we ever thought, about what would happen if there was no friction? Once someone pushed from the back of the bike, the bike would not stop. It would go on. No more fuel was consumed. We used no energy to walk. Since there is no friction, the vehicle does not make any noise. There was no noise pollution. As a result of friction, the elevator rope would not be damaged or torn. What benefits! right?
But if you think a little deeper, you will understand how much complexity would have been created if there was no friction. If there was no friction, the bike would have continued in one stroke. But that bike could not be stopped. Because as I said earlier, there is no friction. That means no brake friction. If there was no friction, the bike would not be able to stay on the road. Its wheel would slide wherever it wanted. If there was no friction, we would not use energy to walk. But we could not stand still. It is not possible to walk on a rainy day if there are no grooves on the bottom of the shoes. Then, if there was no friction, there would be no fear of breaking the elevator rope. But if there is no friction, who will stop the elevator?
With so many everyday examples, we may think that friction is a nuisance for us. But if we think deeply about each of those examples, we will understand that without friction, those events cannot happen. So even though friction is a nuisance to us, it is necessary for us. And that is why friction is said to be a necessary nuisance.

Due to the effects of discovered dark energy, it has been assumed until now that our universe will die through a Big Rip or thermal death. As we know, our universe is gradually expanding. Which has been going on since the Big Frog. The expansion speed of cosmic objects like galaxies, clusters, etc. is supposed to slow down after a period of time under the influence of gravitational force. But the surprising thing is that they do not slow down. Rather, it is increasing gradually. That is, as they are moving away from each other, the speed of their moving away is increasing. Then surely some unknown force is working against the force of gravity. As the gravitational force weakens with expansion, the magnitude of this force becomes stronger. As a result, the tendency of all objects in the universe to move away increases. This unknown energy is called “dark energy”.
According to The Big Rip Theory, there will come a time when the gravitational force will decrease and the effect of dark energy will increase so that the planets inside the galaxy will no longer be bound by their gravitational force. As a result, the planets will move away from each other. And as our universe expands, energy will continue to spread to all points in space. By doing this, the energy density will gradually decrease. At some point, it will be close to zero. And at that moment no power can be used. No interaction will occur. The universe will come to a standstill. The molecules and atoms that make up the universe will also disintegrate. And we will take that moment as the death of this universe.
But this whole thing depends on dark energy. What is dark energy that is not well understood? If understood, we could be more sure, of what is actually going to happen.

Why is the momentum quantity needed?
Think that a truck and a rickshaw are going at the same speed. You are asked to stop both. Which one should use more force to stop? Surely more force will be needed to stop the truck. Because even though the speed of both is the same, the mass of the truck is more, and therefore the inertia is more.Read more
Think that a truck and a rickshaw are going at the same speed. You are asked to stop both. Which one should use more force to stop? Surely more force will be needed to stop the truck. Because even though the speed of both is the same, the mass of the truck is more, and therefore the inertia is more. That is why more force must be applied to stop it or change its inertia. That is, if the mass of an object is greater, its inertia is greater and more force is required to change its inertia.
Again assuming that two rickshaws of the same mass are moving at different speeds. If you are asked to stop two rickshaws, the faster rickshaw will need more force to stop it. Because even though the mass of both the rickshaws is equal, the speed of the rickshaw with higher velocity will be greater. That is why more force must be applied to stop it or change its inertia. That is, even if the velocity of an object is high, its inertia is high and more force is required to change its inertia.
Then we can see that the amount of inertia of an object or the amount of force-changing inertia depends on two quantities. They are mass and velocity. If we multiply the two momentum equations, which is called momentum. But we can say easily or in one word – the one with more momentum has more inertia or more force will be required to change the inertia. This is why we need the momentum equation.
