"Energy in Life" Energy and Life PPT Courseware

group discussion:

What energy is used by the various phenomena in the picture? And try to explain how they move and what effect they produce?

Think about it:

What other energies do you know about life?

Think on your own first, then discuss in groups to complete the form.

Summarize

Sound energy, light energy, electrical energy, thermal energy, magnetic energy, mechanical energy, chemical energy, etc. are all energies, and we cannot live without energy.

The maglev train uses the principle of "magnetic poles with the same name repel each other and magnetic poles with different names attract each other" to completely detach the car body from the track, creating a miracle of near-zero altitude space flight.

advantage:

The train runs suspended above the rails, and the rails do not come into contact with the vehicles. It not only runs fast, but also runs smoothly and comfortably, and is easy to realize automatic control; it has no noise and does not emit harmful exhaust gas, which is conducive to environmental protection; it can save construction costs; operation, Low maintenance and energy costs.

shortcoming:

In 2006, a German maglev-controlled train collided with a maintenance vehicle during a trial run, killing 25 people and seriously injuring four others. This shows that the braking ability of maglev trains in sudden situations is not reliable and is not as good as that of wheel-rail trains.

Tiangong design style:

1. It is the largest manned spacecraft currently developed by China, providing astronauts with a more spacious working and living space.

2. Adopt humanized design to provide astronauts with a comfortable manned environment.

3. The cabin is equipped with humanized personal entertainment facilities. Astronauts can use laptops to send and receive emails, and use video phones to communicate with relatives, friends and colleagues.

The connection between the Heavenly Palace and people’s lives:

The completion of Tiangong-1 has truly "moved" the scientific laboratory to the sky. Utilize the unique microgravity, real environment and favorable altitude of space to carry out space experimental research that cannot be carried out on the ground, thereby benefiting mankind.

A hyperspectral imager is installed on Tiangong-1. If the test is successful, we will not need to conduct random inspections or go to the market to check where there is pollution in the future, but can detect it through remote sensing.
