What else can mechanical energy be converted into, and what can an electric motor convert into mecha

Mechanical energy can be converted into any other form of energy under certain conditions.

Mechanical energy refers to: without considering friction and medium resistance, only the mutual conversion of kinetic energy and potential energy occurs in the object and the total amount of mechanical energy remains unchanged, that is, the increase or decrease of kinetic energy is equal to the decrease or increase of potential energy, that is, the law of conservation of mechanical energy.

Mechanical energy is related to the mechanical motion of the whole object. When there is friction, part of the mechanical energy is converted into internal energy, which is lost in the air, and the other part is converted into kinetic energy or potential energy. So in nature there is no conservation of mechanical energy, then Leonardo da Vinci.

The proposed perpetual motion machine.

It is impossible to be manufactured, i.e. there is no perpetual motion machine.

Kinetic energy unit j (joules.

Definition: The energy that an object has by motion, which can do work on other objects, is called kinetic energy.

The factor that determines the magnitude of kinetic energy is the mass and velocity of the object.

The wind blows the sailboat, and the air does its work on the sailboat; The rushing river washes away the stones, and the water does its work on the stones; The moving steel ball hits the wooden block and pushes it away, and the steel ball does work on the wooden block. Flowing air and water, moving steel balls, they are able to do work, they all have energy. Air, water, and steel balls are able to do work due to motion, and the energy they possess is called kinetic energy.

All moving objects have kinetic energy.

An electric motor is a device that converts electrical energy into mechanical energy. The Tongqing section is often composed of two parts, a stator and a rotor, in which an electric coil is wound on the stator to generate a magnetic field through electrification, and the rotor will rotate or move linearly under the action of the magnetic field, thus converting electrical energy into mechanical energy. According to different working principles and structural forms, the motor can be divided into DC motors, AC motors, stepper motors, and induction motors.

Different types of electric motors are widely used in different occasions and fields, such as vehicles, robots, industrial equipment, and household appliances. <>

1. Why mechanical energy.

It can all be converted into internal energy.

2. It is impossible to convert all mechanical energy into internal energy.

3. Mechanical energy beams and pins cannot all be converted into internal energy.

4. Why mechanical energy can be converted into internal energy.

1.There is a certain amount of error in this statement, and at present, no one can be completely converted into another energy, and there will always be a certain amount of loss in the middle.

2.Because any machine has a coefficient of friction present.

The heat generated by friction is the internal rubber free energy, and the mechanical parts will also have depreciation and loss, which is also converted into internal energy.

3.However, at present, in the calculations in universities and middle schools, because the proportion of energy converted into internal energy is not large, the stove is not counted for the time being.

The speed of the electron is actually not fast (I can't remember, it seems to be only a few meters per second), the energy of the electron is mostly misunderstood as the kinetic energy of the rapid movement of the electron, in fact, it is not, electrical energy refers to the electric potential energy, and the electron with high potential energy has the potential to move towards the low potential energy. Once the circuit is connected, it is impossible for the circuit to be connected with electrons running all the way, and the circuit is turned on that is, the electric field is turned on, and the speed at which the field is established is the real speed of electricity is about the speed of light! The establishment of the electric field is the collective migration of free electrons in the conductors from high potential energy to low potential energy, and the movement of electric acres of pins is not carried out one by one, but almost simultaneously as a whole

The electrons of position 1 move to position 0, and the subsequent number 2 fills the hole of position 1, and this series of processes is completed at the same time, just as the previous car of the train leaves the track section of track 1, and the next car has been filled. The overall performance is the instantaneous patency of the circuit, and this process can be understood as the movement of electrons from one end to the other at the speed established by the field.

The velocity of negatively charged electrons when moving collectively varies depending on the conductive material, but the velocity of the field is always close to the speed of light. The movement of electrons causes a change in the electric field that changes the surrounding magnetic field, i.e., converts the electric potential energy into other forms of energy, and the electron kinetic energy does not convert.

Because there is always a part of the conversion process that will be converted into heat energy, as well as overcoming frictional resistance, etc., and energy is always conserved! So complete conversion is impossible.

It may be converted into heat energy and lost due to friction.

Because there's still heat lost!

This is the concept that mechanical energy can be spontaneously converted into internal energy, but internal energy cannot be spontaneously converted into mechanical energy.

Although mechanical energy can be fully converted into internal energy, internal energy cannot be fully converted into mechanical energy without causing other changes, and the transformation process of mechanical energy and internal energy is directional.
