The eagle needs to consume the (chemical) energy stored in the body and convert it into (kinetic) energy and (heat) energy, if the average speed of the eagle decreases, its potential energy will (decrease), kinetic energy (unchanged), and mechanical energy (decrease) its energy will be converted into (heat) energy and lost in the air. Analyze the transformation of the earliest steam locomotive in the operation process, the steam engine uses coal as fuel, and in the process of coal combustion, (chemical energy) is converted into (heat energy), so that the water vapor forms water vapor, and the water vapor promotes the mechanical movement, and there is (heat) energy into (kinetic) energy, which is the progress of the car.

There are many forms of energy in nature, such as potential energy, bioenergy, thermal energy, solar energy, wind energy, etc.

Solar energy, fossil energy, thermal energy, etc., which can be used directly, are called primary energy. Solar energy can be used to heat hot water, fossil energy such as oil, natural gas, and coal can be directly burned for heating, and the heat energy of hot springs can also be directly used. In this way, solar energy is converted into heat energy, and biological fossil energy is converted into heat energy.

The invention and use of the steam engine in the first industrial revolution was the conversion of chemical energy into the thermal energy of steam, and then into the mechanical energy of the steam engine.

However, after the Second Industrial Revolution, electricity was developed and put to use. It has been found that converting primary energy into secondary energy can better realize transmission and use, and the energy utilization rate of electric energy is higher. The energy utilization rate of the steam engine is only 6%-15%, and a large amount of energy is lost, the efficiency of the gasoline engine is 20%-30%, the efficiency of the diesel engine is 30%-45%, but the efficiency of the electric motor can reach 87% or even higher.

Thanks to the development of electrical theory, the generator is manufactured, the generator can convert mechanical energy into electrical energy, and the thermal power plant is to convert the chemical energy of the fuel into high temperature and high pressure steam thermal energy, steam drives the generator set to work, and the thermal energy is converted into mechanical energy, and the mechanical energy is converted into electrical energy. Hydropower is to build a dam to raise the water level, the potential energy of the water increases, the water flows to impact the turbine rotation, driving the generator set to work, the kinetic energy of the water is converted into mechanical energy, and it is converted into electrical energy. In the second industrial revolution, the generation of a large number of electrical appliances also promoted the development of electrical energy, electric motors can convert electrical energy into mechanical energy, electric lights can convert electrical energy into light energy.

In today's life, based on the use of electrical energy, a large number of electrical appliances convert electrical energy into other forms of energy. It is common to convert electrical energy into light energy, heat energy, and mechanical energy, which involves electrical appliances such as air conditioning compressors, electric fans, electric kettles, and washing machines. In the industrial understanding, but also thanks to the use of electricity, so that electrolysis technology has become possible, electric energy by increasing the voltage, current is more domineering than other energy, many substances that are difficult to obtain by heating, through electric energy.

The production of electrolytic aluminum makes it possible to use metallic aluminum, and the electrolysis of water can produce pure hydrogen and oxygen.

First of all, it is necessary to understand what is the energy conversion method?

Work done and heat transfer are the two ways in which the internal energy of an object is changed. In fact, all forms of energy in nature are transformed into each other in the form of work and heat transfer (including all kinds of radiation).

If the outside world does positive work on the object, does the mechanical energy of the object increase or does the internal energy increase? If an external force does negative work on an object, does the object necessarily lose internal energy or mechanical energy? (Yes).

Energy can be converted into each other, in fact, matter and energy can also be converted into each other.

The various energies we call such as light, electricity, kinetic, thermal, nuclear, solar, biomass, etc., are actually artificially divided. They can transform each other in a variety of ways. For example, heat energy can be converted into kinetic energy by a steam engine, kinetic energy can be converted into electricity by a generator, electrical energy can be converted into light energy through a light bulb, and light energy can be converted into heat energy through a bath bomb.

That's why there is a saying about the "law of conservation of energy". There is no energy in nature out of thin air, which also confirms that a "perpetual motion machine" is impossible. If you want to ask where the initial energy came from, I think it should be the universe 20 billion years ago.

Matter can be converted into energy by fusion or fission, and the formula is energy branch = mass (the square of the speed of light).

Energy is generated by force, and the source of power in the universe is electromagnetic force and gravitational force. At present, what the scientific community wants to solve is to unify the electromagnetic force and the gravitational force into one force, which is called the "Great Unification and Source One Theory".Einstein devoted himself to this research in his later years, and the landlord can take a look at Stephen Hawking's book "A Brief History of Time".

It is recommended that after learning calculus, you will have different feelings.

Energy exists in many forms: kinetic energy, internal energy, potential energy, and so on.

When energy changes from one form to another, we say that energy has been transformed.

For example, when a ball falls from a high place, and the ball is stationary in the air, it has gravitational potential energy, and in the process of falling, the gravitational potential energy decreases and the kinetic energy increases, which we say is the conversion of gravitational potential energy into kinetic energy.

Another example is when you rub your hands, it will heat up. The mechanical energy of our hands is converted into internal energy.

There are two types of energy conversion: transformation and transfer.

As two electrons collide, the collision of an electron by a electron is at rest of the B electron. When experiencing a state where the velocity of two electrons is equal, part of the kinetic energy of an electron"Conversions"is the potential energy common to A, and goes through the final stage: when a electron is at rest and B electron flies out at the speed of a electron (i.e., exchange velocity), the energy has been removed from a electron"Transfer"to b electron.

Usually the transfer has to go through transformation, that is, transformation is the intermediate process of transfer.

After the fuel enters the furnace, the combustion limb is burned, and the heat generated heats the water in the boiler, and the water in the boiler absorbs heat and evaporates, and finally becomes superheated steam with a certain temperature and pressure, and this high-temperature and high-pressure steam is sent to the steam turbine through the pipeline to rotate the steam turbine rotor, and the steam turbine rotor drives the generator rotor to rotate at high speed, so as to send electricity. Therefore, the production process of the thermal power plant is mainly an energy conversion process, that is, fuel chemical energy--- thermal energy, mechanical energy, and electrical energy. Eventually send the electricity out.

After the high-temperature and high-pressure steam expands and works in the turbine liquid dissipator, the pressure and temperature are reduced, and it is discharged into the condenser by the exhaust port and cooled by the cooling water, condensed into water, and the condensate is concentrated in the lower part of the condenser and is pumped to the low-pressure heater and deaerator by the condensate pump, and then the pressure is boosted by the feed water pump after deoxygenation, and then heated by the high-pressure heater and sent to the boiler, so as to cycle power generation.

1. There are many forms of energy: kinetic energy, internal energy, potential energy, etc. 2. When energy changes from one form to another, it is said that energy has been transformed.

3. For example, when the ball falls from a high place and the ball is stationary in the air, it has gravitational potential energy, and in the process of falling, the gravitational potential energy decreases and the kinetic energy increases, which is the conversion of gravitational potential energy into kinetic energy.

4. There are two types of energy conversion: transformation and transfer.

5. If two electrons collide, the collision of a electron is a resting B electron. When two electrons have equal velocities, part of the kinetic energy of electrons A is converted into potential energy common to A, and the energy has been transferred from electrons A to electrons B when electrons are at rest and electrons B fly out at the speed of electrons A (i.e., exchange velocity).

6. The usual transfer has to go through transformation, that is, transformation is the intermediate process of transfer.
